We stayed 3 days in this small apartment but we enjoyed it. We don't met Valeriya but Serdar helped us to check in and to find a safe and private parking for 60 lira for 24 hours.
The room with two beds has a view of the street and noise at night but there is an air conditioner for hot summer days. While the other room with a double bed is absolutely quiet. The apartment is located on the second floor and if you have heavy suitcases, don't worry as you have an elevator.
The apartment is located near the main Isliklar street in Istanbul, which has many restaurants, pastry shops, and everything for those who want luxury and for those who want simplicity.
Valeriya was available and answered messages very quickly. We recommend Valeriya's apartment
