The stay at Vahram's place was really good. The apartment is very clean and modern and the room with the balcony was perfect for one person. Vahram is a really open and helpful host and also gives some suggestions for activities.
I stayed for one week and had basically everything I needed. The area around the apartment is full of bars, cafes and good restaurants. Couple of minutes away there is a supermarket and also the harbour at the seaside. 10 Minutes walk to the ferrys and to the center of Kadikoy.
To sum up, I really felt comfortable at Vahrams place and would book another stay there anytime :)
