The place is great. You are getting two small private rooms - a bedroom and a sitting room.
The apartment is clean and spacious, the hosts are very kind and the location is great - 10 min walking to Istiklal.
The rooms are a bit dark as windows look at the wall of another building. There can also be issues with the internet in the room but there is always a good connection in the living room.
Overall, I'm very happy with my stay and I would stay here again :)
