General for Finland:
1. Be polite, but genuinely. Finns hate show-offs, arrogant and rude people, and pretenders.
2. Don't lie. Finns hate dishonesty and a caught liar have to do much to regain other peoples' trust.
2b. Don't say "nice to meet you", if you don't mean it. Finns will notice it and you're caught with a lie.
3. Do not cheek-kiss or hug on first meet. Shake hands.
4. Finns have a quite plain look on the street and usually don't smile much, but that doesn't mean we are unfriendly and rude. If you're a tourist and need help, people are often glad to help you, especially if you start with "excuse me, could you help me..."
5. Virtually all people under 60 speak English.
6. Don't interrupt people, even in heated debates. It's considered rude and is a sign that you're not interested in what the other person says. Wait until the other one is about to finish and then go ahead.
7. A short moment of silence between speaking is not awkward for Finns. A moment's silence is a sign that you're giving a thought about what the other person said (even if you really aren't).
8. Do not call Finns Russians or Swedes or compare Finland with these countries. Caught between these two countries it's a small miracle the Finnish culture exists at all today. Finland have a very traumatic history with Russia with numerous wars and oppression, and call Finland the "little brother" of Sweden is something you don't want to do. The Finns are proud of their country and to be Finns. Swedes and Russians don't experience any racism or rudeness, though.
9. The Finns are the most active newspaper-readers in the world and they probably know more about your country than you know about Finland. Try to learn some key figures and events of Finnish history and culture. People will be delighted.
10. UNDER ANY CIRCUMSTANCES DON'T ask/claim if Finland took part in the holocaust, went nazi or turned communist after WWII. Because we didn't. Neither should you say that Finland is in Eastern Europe.
11. UNDER ANY CIRCUMSTANCES DON'T discuss the Finnish Civil War of 1918, if you aren't certain that the other one is receptive. Over 22,000 people died from execution and in prison camps, more than double than in the actual fighting, and the events are still traumatic for some people.
12. Finns are rather straightforward and blunt, and probably less PC than in your country. Finns are generally happy to discuss almost anything but those above + money. If you're starting a heated political debate, you might get a "in your face" answer, so suck it up and reply with a handful of arguments. Don't get insulted for minor things.
13. Freedom of speech and press is very old in Finland. the Finns usually speak very freely and people often have a lot of opinions. We don't like to play with words but usually say things as they are. It's not considered rude to speak your mind.
14. Business is business, leisure is leisure. If you're doing business, expect to go straight down to the matter and get it over with. Then you can go for dinner. Do not suggest a long lunch and a couple of beers in the middle of business.
15. A deal is a deal, and a promise should be kept. A handshake is as valid as a written contract. Also, be punctual. 19:00 means 19:00, not 19:30 or 20:00.
16. UNDER ANY CIRCUMSTANCES DON'T drink and drive. The consequences and punishments are severe and will cause you real trouble.
17. Prepare to drink a lot of coffee. Finns drink the most coffee in the world, and you'll be served coffee everywhere. You can politely decline, and ask for something else.
18. The Finnish culture is very relaxed and relatively classless. There's not a strict dress-code or many taboos, faux-pas's or strict social norms. Don't be scared to do something stupid, because most likely you won't. If you do, it's not a big deal and people will smile. Finland follows the Western European table manners and other, so behave accordingly.
19. Take your shoes off when visiting a home
20. Be prepared to go to a sauna. Naked.
For Helsinki:
1. The core historical center is a tourist trap and the prices sky-high. Venture a bit away and restaurant/bar prices will drop surprisingly fast.

2. Taxis in Helsinki are extremely expensive, but the public transport is excellent, so learn the tram system which is the easiest way of travel. A single ticket is only 2.2€ and you can travel for an hour unlimitedly with it. You'll save a lot of money. Consider a day, weekend or serial card. If only traveling in Helsinki, don't even consider in renting a car.

3. The night buses and the metro on weekends can appear quite rugged. But they're completely safe. Be prepared to encounter a bus filled with drunk people shouting, singing, eating and puking.
4. Two predator grocery store chains have virtually a cartel in whole of Finland and controls 85% of the market. If on a tight budget, don't go hunting for cheap groceries, you'll only waste your time. The prices are exactly the same everywhere.
5. In chain stores, grocery stores and gas stations the list price is not negotiable. In independent stores, market squares or market halls you can try your luck. Sometimes it's possible, sometimes not. Exception: if buying expensive electronics, furniture, sports equipment or souvenirs, you can bargain. Sometimes it works, sometimes don't.
6. UNDER ANY CIRCUMSTANCES DON'T try to bribe anyone, especially a government official. It's a criminal offense.
7. Don't argue with night club bouncers. Just don't. Serves no good and the police won't help you.
8. UNDER ANY CIRCUMSTANCES DON'T venture into the park behind the Central Railway Station during nighttime. If not necessary, avoid the Central Railway Station during weekend nights completely.
9. Don't get into trouble or hefty arguments in districts like Kallio, Vallila, Sörnäinen and Hakaniemi. Serves no good and you can get a bloody nose. Otherwise the streets are relatively safe. You'll also find the most cheap booze in Helsinki here, so it's worth a visit. Even the most shady joints are safe, just look after you belongings.
10. Helsinki has no "no-go zones", but avoid the far Eastern suburbs during nighttime. There's nothing to see there anyway.
11. Avoid illegal taxis, unless you're a group of muscular men. If traveling alone, avoid completely.
12. Scammers are something I encounter maybe once a year, and are very rare. Pickpockets operate only in the most core crowded areas, so no need to be paranoid. Overall, Helsinki is probably safer than your city of 600,000 people.
13. The archipelago and coasts are infested with tick. Don't wander into bushy areas with shots and t-shirts if not necessary. No need to get the Lyme disease as a souvenir.
14. The bike lane is for bikes only. Don't walk on them, thank you.
15. Drinking alcohol in public is a tricky matter. It's legal if you sit in a park or have a picnic or something, but not if standing on a street corner harassing bystanders. Not allowed in public transport either.
16. Smoking pot in public is illegal and will give you a fine. There's no open-air drug markets in Helsinki.
17. The Police is uncorrupted and respected. You can always ask one for help if needed (except asking them for a ride
). Security guards on the other hand are not Gendarmerie type government officials, but hired by private companies. Don't expect to get much help from them, but depends on the person and his/her mood.
18. When boarding an elevator, train, tram or similar, wait in line and wait for the people to hop off before you enter, thank you.
19. Ask around. Some really cool events can be quite underground and poorly advertised. The rumor mill and social media is effective and as I said earlier, people are always happy to help out a tourist.
20. The inverted V-sign means nothing in Finland, so don't get offended if someone shows you that sign. It means two.
Well, that's more than enough, I think!
Oh, one more thing. Helsinki is a very clean city and proud of it. Don't litter, but look out for the nearest garbage bin, thank you.
