The apartment has no sound proofing at all. I could hear people chatting, coughing, snoring, using toilets all night long. The floors are squeaking so it feels like people are walking over your head. People upstairs were chatting, singing (or praying) way after midnight. Someone's alarm was going off at 5:40 am, then at 6 am. Sleepless night and constant noise, unwanted listening to conversations (every word!) of other people around the house were very disappointing.
The studio itself is clean. The neighbourhood itself is nice and quite. The check-in was easy but if you are looking for a quiet place for a good night rest, I wouldn't recommend it.
