The place was exactly the same, as it was shown in the photo (just seemed a little bit smaller). We came late, after 20:00, but manager met us and have keys for the room. The apartment is stylish, and there is all, that you will need for a short term stay - for me and my boyfriend it was comfortable!
We decided to stay one more night in Istanbul, so we asked a manager to prolongate our stay, and there was no any problems with, we just needed to change a room.
Also, there is a nice restaurant at the the same house, which we visited two times and liked a lot - recommend you to try it too, it's called Mivan, and it has a good rating. And by the way, they cooperate with hotel and you even can order by phone and they can bring you your food straight in your room:)
