Dont even think twice, you should BOOK Muhammeds home immediately. It is a wonderful home and its designed very beautifully. The location is fabulous, you are just close enough to Taksim to go but just far enough that you dont have to deal with Taksim. You can be at Galata tower in about 10 min walking and after that Karakoy which is a cool place to go for drinks. Muhammed and Erme are amazing guys who will treat you with respect and make you feel at home when you are they. Erme was always around if i needed him and to answer all my questions. He was amazing and of course the apartment was clean and well designed for one maybe two people. Beautiful place I will for sure be returning here on my next stay in Istanbul.
