The apartment is good, location is excellent! You do have to use the stairs to get to the 4th floor, which was a bit hard for us (we had big luggage), but definitely not impossible! We had an issue with the heating system which didn't work for most of the time, and the apartment was very cold. Oleg did all he could to fix it, he was very attentive, but it did make our stay a bit uncomfortable since we had someone over every few minutes during the evening to check the issue. During the last hours of our stay, the heating worked just fine. Leaving that issue behind, the rest of our stay was fine.
