When we arrived the wet bedsheets from the previous people were hanging all over the place. It made the air very dry. And since you can't open the windows because of the metal bars (!!!) in front of them (can’t see it in the pictures), the air wasn’t that breathable. Since there are no smoke alarms either and the electronic door doesn’t work properly, you could get caught in case of a fire.
Some of the things promised in the description were missing. Basically, it is just what previous guests have left there. It also wasn’t that clean to begin with. The floors were sticky, there were dirty dishes in the cupboard, mostly unwashed bedsheets (one bed had two on top of each other, probably for faster changing) when we arrived.
On the plus side, it was decently priced and the communication with Katya was quick and without a problem. The apartment is pretty close to public transportation, which is also a plus.
