Mehmet is a great host, always available to help, and very friendly!
The apartment is great, I'd definitely stay there again. It is close to a variety of places like pubs and restaurants, and easy to find cabs and other transportations. It was my first time in Istanbul and I loved it.
It was a long-term stay and because of some government-related bureaucracies against Airbnb, I had to sign in a contract, stating that I'd stay for at least 1 year, but it wasn't a problem at all, it was safe and hassle-free, so don't worry if you have to do the same!
