Gökhan and his flatmates were kind and help me in everything I needed.
The room is big, with good natural light and the bed is confortable.
This part of the asian side of Istanbul is very cosy. Is full of tea places and restaurant. The city ferry boat departs a minute away from the house to the city centre (next to the Spice Bazaar). It costs only 8 Turkish lira with the Istanbul card. The location is thus very good.
I was very confortable there and would have stayed longer if the room was not booked already. Thanks Gökhan & co for everything :)
