We just left this place. We travelled with kids. First of all I would like to say, before we even left our country Can made sure that we had a ride to get to his place. Since we didn't have any he ordered us (6 people in our group, including 2 children) a taxi and collected money the next day.
The location is great. It is right in the center of everything, but away from all the noise. Since it is a dead end, only few cars drive by that small street. There is a ferry, that leaves from Arnavutkoy Iskelesi station, literally just across the street, that takes you to Istanbul. We saw many tourists and local use that type of transportation, because the traffic is pretty bad in the afternoon.
Can is also is very fast to respond to any questions that we had. It is also a very safe area. Even if you forget to lock the door when you are inside, the way the lock is made, is that you can't open from outside, someone has to open for you from inside.
