Great location in Istanbul. We stayed over a week and overall I would recommend this place! Walking distance from main attractions and there are markets, shops and good restaurants in the neighborhoods!
The living room was quite spacious, which was convenient for us to spend time together with the family. Two the bedrooms are also spacious and facing the main street while the third one is a bit smaller and face the inner side which can become noisy at night. The beds and pillows were quite comfortable (I appreciate to have firm pillows!). On the other hand, the toilet is rather small and the elevator is quite an experience...a bit scary but all in all it can fit two people at the time which is convenient for elderly people as the apartment is in the 6th floor.
