It was our first independent trip (10 days, without tour agency) and we had a great experience here.
First Kamil was delicate and responsive in my first experience in airbnb (I made couple mistakes and he helped me) and when we arrived everything was just perfect. Everybody of his team is friendly and helps a lot - we were given an Istanbul card for tram/bus, shown a good cheap places with delicious food and everybody was really friendly and helped a lot (especially Hasan).
They speak several languages (3-5-10? :) ), reliable and can help 24/7.
Airport transfer to both ways was reliable too.

The location is perfect, just in the city center, walking distance to all interesting places. The room is clean and comfortable, just like on photo and cleaned every day.

I will recommend this place to my friends when they will go to Istanbul.

Thanks a lot, Kamil and Hasan!
