I stayed in Barans apartement in Kadıköy for a couple of nights.
He is a very nice and caring host! He also has great tips and it is always nice to have a chat with him.
The rooms are in a great location to go out in Kadıköy and explore the city from there. The ferries to the European side are very close and you have a lot of bars and restaurants around and the rooms are very cheap for this location ;)
