Hi Mary,
Tashkent is a very nice city, quite, and safe with good restaurants, mild climate. It does get hot in summer months - over 40 celcius but the climate is dry so if you have an AC, you will do fine. It's not as fancy and developed as Dubai but it is a good, safe place where you will live in a relaxed tempo. There are beautiful montains in Tashkent, lots of places to hike. Prices are much lower than in Dubai for everything. People in Uzbekistan are generally nice and warm. Food is good, at least I like it.
Make sure you take care of your registration when you arrive here because fines are high if you fail to do this in time. You can buy a car for 15-20k USD, a nice one and sell it when you leave.
Good thing about Tashkent is that it is very safe and very clean.
Hope this was helpful
