The room was very bright and larger than I expected. It was also clean and had a comfortable mattress. There is a very sweet cat who often came into the room while I was staying there, and she loves to play! The bathroom was a little grimy, and the toilet is in a separate room across the hall from the sink and shower. Using the toilet was a little strange because there were 2 doors to it: one to go into the hallway, and the other one into another bedroom. The only issue was that in order for the other person to go into their bedroom it was necessary to either walk through the room I was staying in or the toilet. The door that leads to the other bedroom from the toilet also does not completely shut, which made it a little awkward for me as well.
The apartment is on the 4th floor of the building, with thin and steep stairs, and no elevator, so probably not the best choice if you have a lot of heavy bags.
Nikolay was very responsive, though, and even though I was not able to meet him, he also made sure to respond to me as quickly as possible even while he was on vacation.
