Registon square is must-to-go place for tourists in Samarkand. You can see ancient architecture, go to shopping. At 21:00 local time you can watch some laser show.
Vey good hotel with nice rooms. Clean. Have good choice of food for breakfast. Only problem is thin walls, sometime you can hear noises from other rooms.
I traveled to Sochi for the first time. The airport is good. Passed the passport and customs control easily. But you have to wait for long time to pass passport control due to big lines.
