East Nashville is one of many increasingly good options if you want to live near downtown and midtown. There are so many different parts of East Nashville (some safer and more polished than others), that I would take great care to research the East Nashville location you're considering.
Some of the areas that it sounds like you might also want to consider are Belmont, 12South, Hillsboro Village, Germantown/Salemtown, West End Park, Sylvan Park, the Gulch and Green Hills. Some of these can be pricey while others can still be a bit questionable in certain areas. Take some time to evaluate all your housing options well while you're here and look at many different options from craigslist, apartment selection services,etc. If you don't mind a short commute and would prefer more space for a cheaper price, then you might want to also consider some areas a little further out like Bellevue, Nipper's Corner or Hermitage.
In regards to the hotel and tourism industry, you heard correct. The hotel industry is booming here and will continue to as plans are full steam ahead now on the new Music City Center. The new convention center alone is probably going to bring two new large (1,000+ room) hotels. Boutique hotels are becoming popular here. Hotel Indigo opened on West End not too long ago and another one is opening up downtown. Across the street from Indigo, an office building along West End is now a shell waiting to be turned into a boutique Hutton Hotel. An Intercontinental Hotel will be a component to the West End Summit. In fact, hotels are just sprouting up all around West End and Midtown lately. Of course, there's always the enormous
Gaylord Opryland Resort which is also adding more hotel and convention space.
As far as the nightlife is concerned, a friend of mine swears by this karaoke bar named
Ms. Kelli's in Printer's Alley. However, I've never been so I couldn't tell you what it's like. The majority of the gay nightlife is along Church Street in Midtown. Go to
Tribe if you like a bar setting with some great martinis. Hit up
Play next door if you want a killer drag show and some great dance music. Take a stroll down to street to Blu if you're more into an urban/hip hop gay club. Also, the bars in the Gulch and around Midtown seem to be pretty popular around here.
Good luck on your move and apartment search and congrats to your partner on his scholarships!
