Summary: Very calm and quiet place, clean and comfortable, and great value for the price. The kitchen is large and well equipped with everything you need. The location is excellent — just a few minutes’ walk to the метро station and grocery stores. The host is very friendly and helpful, which made the stay even better. Thank you for a lovely stay!
