Birol is an Amazing Host, you can ask whatever you need from him and he will provide for you.
The Place was clean but it was not as fancy as I expect.
The Street from of the house will be close daily at 12:00 PM so if you have a child or you need the taxi bring your logage at door step, it whold not be possible. It is near Galat, the street is very alive and you can experience Istanbul night life and on the other hand you may have some sound difficulties for sleeping.
