Great place to stay in general. Very good deal for the price at an excellent location, a few steps away from Taksim Square and Istiklal Street.
I didn't meet Tayfun, but Atahan was an incredible host. He would recommend me several places to visit around the area, and he would respond fast to any request.
I had a little room cleanliness issue when arrived, but Atahan fixed quickly and gave me a different room, which was even better than the one I booked, so much appreciated.
Really good overall stay and I would definitely repeat.
