The apartment is really cozy and clean. There are carpets, candles and other nice things that make your feel very comfortable. Daniel is very nice and hospitable person. He offered all his food in a refrigerator. We made breakfasts on a kitchen, it is small but you don't need more. There is a wonderful terrace with the view of the city (roofs) and Galata tower, and there is a small balcony on the other side with the view of Bosphorus. In the morning you wake up, open curtains and see a sunrise on a Bosphorus. Amazing experience!
The location is very convenient. It's an old area and you will love its spirit.
The only small thing was synthetic blanket that made me sweated at night but then I used another one and it was fine. Probably this is only my problem, and it will not bother you.
I would definitely recommend the place to my friends, and would come back again!
