I am a digital nomad from Germany and I have stayed at Mücahit's place for almost two weeks.
As a result I can say that Mücahit is the ideal airbnb host, if you are planning to stay in Istanbul, because of several reasons:
First of all, he has a great small apparment, that is ideal for solo travelers.
And second, and most important of all, Mücahit is a really great, trustworthy and cool person - with whom you can build real friendship!
P.S.: looking forward to stay at your place again in Istanbul :-D
