Convenient location: clean air, minimum cars, the nearest beach with access to the open Sea of Azov, not many people on the beach. The beach itself and the sea are clean. There are few shelters from the sun.
The staff is very friendly. Separately, I would like to mention the instructor in therapeutic gymnastics - one of the best teachers for any level of training.
The only thing I didn't like was the level of competence of the nurses: I took blood for sugar from 3 times - I can't use a glucose meter. They just grumble when you come to them to take a pill prescribed by the attending physician of the sanatorium - for some reason they believe that the pills should be brought by vacationers in advance)
The dining room is on the middle level. There is enough food for a normal person. The variety is not great: there were not always enough fresh vegetables in the summer. Otherwise, there were no incidents or misunderstandings.
The room was always clean. There is a net on the balcony door. There were no insects in the room in principle, although I lived on the 1st floor. Everything worked: shower, TV, refrigerator, light. In general, the level of my room and the entire sanatorium is the USSR.
