Sadly, I had to cancel my reservation at the same day I entered although I had reserved it for more than a week! If you need just a bed to sleep, you can consider this place as a choice because it is close to Taksim square (the only advantage maybe).
The place was not clean! There was a strange smell inside. The air conditioner was not working properly. The door to the dusty backyard was broken so it was not possible to open it easily and a part of its door was covered by plastics! The zone was really unsafe and you feel uncomfortable when you walk in that neighborhood!
