I highly recommend this place. The location is very advantageous for all kind of people - tourists or people working in Istanbul. You can easily access Istanbul center / metro / ferry to Asian part. When needed you do not have to use the bus or taxi but you can walk there from the center.
Compared to other apartments this place has high-class interior. You will feel there as you are at home and not in a hostel.
The owner of the apartment - Murat - is a friendly person ready to help you with anything if needed (foreign citizens will appreciate :-)
