The location is unbeatable! The room was small, but fine if you are using the place just mainly to sleep. The apartment across the window is currently unoccupied so you also have some decent privacy.
One big negative that guests should know about is that there are cockroaches. We had planned on using the stove to cook but the bug problem turned us off.
Another issue is communication: we came back in one morning to find all of our food taken out of the refrigerator and sitting out on the table. When I contacted Yulia, she told us that the refrigerator was going to be changed. She responded quickly and apologized, but there had been no prior communication that anyone was going to be in the room besides us. We ended up throwing most of the food out because we didn't know if the cockroaches had gotten into it, and we had to keep a few things inside the microwave for the rest of the day due to the fridge change. I get that this is necessary maintenance, but guests should be informed when workers are entering the room so (guests may wish to put electronics out of sight, for example).
Another factor for guests with children to consider is that the foyer does sometimes have rough people in it, but the security desk seems on top of any problems.
