Ugur is a nice host and did his best to make us feel confortable, always asking if everything was ok. The appartment was very clean and looks pretty much like in the pictures. Istanbul can be very hot and you may become disapointed that theres no airconditioning in the room, but dont worry: the one is the living room can easily reach the bedroom. Just leave the door a bit open.

The appartment decently located, near istiklaw(or something like that), which is the main street in istambul to eat and buy things.
You can walk to the main atractions in the city just walking(I didnt use the transport card that Ugur leaves in the appartment, but its there and its cheaper to use it if you are going to use the public transport).
As another reviewer said, theres always some kids near the appartment, but they just hang in the area. Dont worry.
There are also near markets, including a small carrefour.
I think that, considering the size of the flat and the relative ease to go to the main areas in istanbul, its a great value and I would recommend staying there.
