Well, this is one of the best airbnb choices in Istanbul. Large centrally located flat fully equipped with everything needed. Even the dish washing machine. Internet was stable and fast. Kalorifer worked well, there were heating and hot water all the time. As a bonus - cats band on the balcony) be careful - they're trying to force inside each time you open the balcony door:) Communication was smooth, Civan's brother Şeref provided us with the keys and explained everything about the flat, then also helped us to order some drinking water which was delivered right to the door. All in all, we had a great experience and can recommend the host and the apartment for the long term stay in Istanbul.
