Very communicative and friendly owners! Location is just perfect, right in the center of Beyoglu/Cihangir and literally nearby everything.
As for the apartment itself, it is a bit outdated to be honest. The pictures were very promising, but in reality the apartment was not in the best condition. But the terrace is lovely, and lots of bedrooms!
Since it was cold, I was missing a common area in the apartment too where you could sit comfortably with friends.
