Ilhan and Taha (the guy, who was responsible for the building) were really nice guys and they were always ready to help. They answered the messages very fast.
The place was very well designed and clean.
The neighborhood was also good. You can buy fresh baked bread in a minute or two, because bakery is the next door neighbor :-).
There are two supermarkets in this street and bigger supermarket only 5 min walking away.
You can go to istiklal street in 13 minutes.
I will definitely choose this place again in my next trip to istanbul.
