I just got back from Accra on Saturday.
I was born and raised in the US but my father is from there so I have a lot of family as well as some friends in Accra (the friends were raised in the US but moved back 3-5 years ago). The last time I was in Ghana was 20 years ago as a teen.
Here are some of my observations:
Infrastructure has improved considerably. Main roads and highways are well maintained but the side streets are still dirt roads and poorly maintained. The exception is in the ultra wealthy neighborhoods that are full of expats like Airport City. That area has million dollar estates (yes million USD). Driving around that area I don't think I encountered a single dirt road.
The traffic is a nightmare! There is no mass transportation. It can take you 3 hours to drive 15 miles!!! Yes there are taxis (but they are known to cheat you) and minivan busses called tro-tros (for the adventurous foreigners but widely used by locals) but car is really the only way to get around. Driving itself is very intimidating. While I'm an aggressive driver, I live/drive in NYC, I would not want to deal with Accra traffic. If I lived there is absolutely have a driver. One can hire a driver for about $100/month. That's what my friend's mom pays her guy.
Oh and while there are street names, it's a "new thing" so nobody goes by street names. With the exception of the main roads you literally have to give directions by noting landmarks like "turn right at the mango tree". I'm serious.
Several ultra wealthy areas are emerging in Accra. I mentioned Airport but also Labani, East Leagon, Cantonments. Labadi and East Leagon you'll find grand estates. In Airport and Cantonments you'll find estates and modern high rise apartments and condos that look like they'd fit in to NYC, Chicago, San Francisco, or London. These are exactly who the condos are appealing to: expats or others raised abroad. The prices are targeting them too. The cheapest condo you'll find is around $75,000 for a studio. The three bedroom condos are $300,000+. Still I've seen other condos listed for close to $1 million! A lot of foreign born/raised people (Ghanaian or otherwise) are pumping money into Accra's real estate market. There is a huge boom. Building of these condos are all over these trendy neighborhoods. I also saw several gated communities under construction in other neighborhoods. The communities are similar to the ones you find all over places like Virginia, North Carolina, etc.
No brown outs happened while I was in Accra. Electricity rationing is very common despite the fact that there is a huge hydroelectric dam north of the city! I've heard the theory as to why there is electricity rationing despite the dam having the capacity to power half of the country (the govt is selling the electricity to neighboring countries) but I don't know if that's no longer an issue or if there was less rationing because it's an election year in Ghana.
Shopping amenities are getting up to par with US standards. The supermarket Shoprite has several locations in Accra. There are also other familiar retail stores like Apple, and Nike in the malls. Accra now has a few "American style" shopping malls that are identical to what you'd find in the US.
There are also many hip and trendy bars, clubs and restaurants. My cousin was hell bent on showing me Accra night life and it was impressive. We went to four high end restaurants. By high end I mean high end by western standards. One club frequented by multinationals- and it was the type of club you'd find in any western city and one "locals" spot. The locals spot was outdoors and had a live band. Besides that, there are lists full of "what's hot" in Accra.

Ghana like most developing countries (hell even developed countries!!) has a problem with corruption. However I only encountered one instance of a police asking my cousin for money. This was at a traffic stop. He just said something to my cousin and made a hand gesture and my cousin already had money in his front pocket, just a few small bills probably the equivalent to $3, and gave it to the police and he waved us on.
Those are surface observations and based on those, it would appear to be great. I think the hard transition for anyone raised in the west is going to be one of culture. For example everyone speaks English but it would be in your best interest to learn Ga. Ga is a tonal language so it can be difficult to master. Twi is more widely spoken in Ghana, and easier to learn, but Accra is a Ga area and is the language spoken. As an aside, most people will speak 4-5 languages fluently which made me look like an idiot with my command of only English. Also west African culture is collective in nature. Western culture is individualistic. That doesn't sound too challenging but trust me it is! I've had so many clashes within my family because my concept of self is very different.
