Bahri and his wife were very helpful and friendly. The apartment is cute, with a nice view, and located in a nice neighborhood, with 5-10 minutes to the ferry to Sultanahmed (this way includes appr. 130 stairs, so if you are - like us - with stroller and kid there; good luck! :-)). The big terrace is a really good place to sit and enjoy the sunny evenings and the view to the european side of the city.
The apartment was very nice and clean, and has two bedrooms. It lacks though a living room or any place to sit cosy, apart from thr terrace.
We enjoyed our stay very much, and can recommend it.
