We had a wonderful stay in Simay's apartment. the views from all rooms and especially the roof top were amazing, best in Istanbul. the place was done up to a high standard and was very clean. the beds were comfortable, there was all sort of house hold supplies available like washing up liquid, tea, sugar, dish washer liquid, cleaners, etc.
I particularly liked the roof top bubble living room, it was so cozy with amazing views.
the location is very close to Galataport where you will find nice restaurant at an amazing view of the Busphorus. also, Karakoy is full of nice streets full of restaurants and bars for night life.
Simay was a great host, she responded to our requests promptly and made our stay pleasant.
