First line. Price-quality ratio. Green area. Location. There are many shops and cafes around, close to bus stops from which you can go to see the sights of Sanya.
Excellent travel agency. I have been using their services for four years. I buy a tour and get all the information online or by phone and no problems (I have never visited the Kaliningrad office of Alohatur in 4 years). The best prices for tours in the Kaliningrad region.
