The location is awesome. It’s close to Hagia Sofia, grand bazar and the tram station, and surrounded by lots of restaurants, hotels, and stores.
The apartment is old but cozy.
It’s in the second floor with a bit uncomfortable stairs. The two things I didn’t like were the carpets and sofa (very old and a bit dirty) and the bathroom sink (small).
Deniz was a nice and helpful host.
Overall, I recommend this place.
