We had a great stay at Hikmets airbnb, the communication was also very good, he and his son speak speak english very well, which isn't that common in istanbul.
He offered us transportation from the airport, which was quite convinient, as the airport is about 70km away from the airbnb.
His son got us Sim cards, and he told us about the area, we could have even rented a scooter from him.
All in all two very friendly hosts!
now for the downsides.
The air quality in the apartment gets very bad. If you come back after spending a couple hours outside, the first thing you should do is to open the window, make sure no cat comes inside.
The apartment in general seemed somewhat deteriorated, old furniture, holes in the wall, one AC didn't work.
The beds and towels seemed to be clean though and they even offered some kind of room service after a couple of days, which we declined.
