My friend and I really enjoyed our stay, we arrived late at night and were welcomed by a very nice couple who live right next door (we were on the ground floor) and were available anytime we were struggling/needed something.
The room is nice and clean, just as it's shown in the pictures, the wifi is fast which was very convenient for me as I had to do so work from home and the AC worked just fine.
I would recommend this place for anyone but keep it in mind that to get there you have to walk down a steep (hill?), then again almost all of Istanbul is like that so you get used to it ^^
