Mali is a perfect host and his place is as well a perfect base for your visit in Istanbul. It's just few minutes from all the central Kadikoy areas and also to the Metro bus station.
Dealing with Mali and his girlfriend Sinem is very easy and pleasant as they're very nice and kind people, answer quickly to messages and are always available to help with any information you may need.
I'm glad I chose Mali's place and I would do it again :)
