@Konstanz I know almost none of the language. As an English speaker I find that most younger people have good English, while older people know Russian.
Most people in international type places (high end restaurant, supermarket, etc.) speak enough English. Similar to SE Asia in that respect. If someone doesn't speak much English and you don't speak Georgian, there's not the latent hatred that Brits experience in parts of Spain and France. People here
really want to know if you like Georgia and if you do, then they like you.
Comparing Georgia to Dubai is like comparing a Sicilian village to Las Vegas. I like both, but many people don't. My impression is that people fall in love with Dubai's skyscrapers and slick restaurants in 6* hotels, but the veneer wears off after a while and a lot of (but not all) expats really learn to hate the place. People I've met seem to warm to Georgia over time. I've heard similar arguments about Singapore (soulless, empty, commercial, etc. etc.) vs rural Thailand (potholes, unreliable electricity and water, stray dogs, etc. etc.). It's down to personal taste.
@iloveyouguys it really depends what you like. Tbilisi is quite metropolitan but with lots of potholes. A great place if you like opera, live jazz, family style restaurants. Vake has higher end (and price) restaurants and apartments, Saburtalo has more Westerners, Rustaveli has bars and a lively vibe, old town and Marjianishvili also have a busy but more touristy vibe. Isani/Samgori/Varketeli has no real tourist value, but you can walk up to Tbilisi Sea (think reservoir) and get out of the city. The metro is fast, cheap and efficient and I don't like sitting in traffic so being a short walk from a station is important to me.
I haven't been to Batumi. It seems to be where people go for nightclubs and dodgy massages. Rustav is is cheap and not too far from Tbilisi.
If you want to learn the language, experience village life, marry a nice Georgian and run a small vineyard with your 10 Georgian Children, then the rest of the country should be fine.
I hope this isn't all too off topic. If someone wants residence by investment then I think the local milieu is kind of relevant.
