The place is very comfortably located - right next street to the vibrant Beshiktash district and ferry terminal but at the same time very quite because of location on a very small backstreet. Also, you can reach Taksim on foot just in 15-20 min.
The room was very spacious and fresh - thanks to windows to the backstreet - I didn't use airconditioner, no any smells from the street at the same time. My sleep was very comfortable.
I Will recommend this place and stay here during next my visit to Istanbul.
