Beautiful and modern apartment in centric location, with good WiFi, AC (really important in Istanbul during summer!) and very clean. However, the windows barely isolate the noise from the street, which is quite annoying to sleep, and the flat is much smaller than what you would expect from the pictures. The last negative point would be the lack of elevator and the steep stairs, making so exhausting and hard to carry your luggage up. Anyway, in general we were happy with our stay.
