The apartment was nice and clean. I stayed there in July, which is the beginning of winter. Expect it to be cold since the place doesn't have heating.
There is no private access to the building, meaning someone has to open the main door. One time, I had a late return from an outing and had to bang on the door for 10 minutes in the cold. There was another person inside trying to get out, and we both had to wait for a child to wake up and open the main door.
The apartment is priced very low for a reason. After two nights, I ended up leaving the place and going to a hotel.
