Akif's place was fantastic. We stayed for over a week and it was lovely to come home after a long day of museums. The location is super ideal for getting all over the city, and the place is even better and more hip than the photos. That couch is SO COMFY. Oooh also there is a really nice restaurant down the street called Paydidar (spelling? memory?). Also you get a sweet workout from the three flights of stairs.
Akif was available every second for any questions that we had, and even surprised us with a bottle of wine! Wifi worked great, never ran out of hot water, bedding for days, it has everything you need. I would highly recommend staying at his place. Very comfortable - lots of room for our 4 person group.
