The apartment was great, just like shown in the photos.
It is situated in a great location, just across Vadi İstanbul with restaurants and shops. You can find a lot of things to do with or without a car. If you have a car, though, it is in the middle of İstanbul, very convenient to drive to many places within 15-20 minutes.
Kaneshka is extremely responsive, he responded within 10 mins to any inquiries we've had.
Overall, I'd definitely stay here again if I were to visit İstanbul. Great location, great value, great host.
