My brother and I stayed at the apartment for 4 nights. The communication beforehand was quite quick and kind. However we had problems finding the right house because the number of the house cannot be seen easily at first look when passing by it. We also experienced problems opening the doors sometimes with the key. It sometimes seemed to be stuck a little. Olenkas family helped us out with that.
The apartment was very clean. We were even given new and clean sheets for the couch as well as freshly washed towels.
Unfortunately it took us at least an hour to reach the Times square every day. The buses are not always on time and traffic causes delays. Furthermore i is difficult to reach the apartment at night or late evening because the metro does not drive anymore after a certain time.
