Gizem's place is exactly as advertised, and a really wonderful place to stay in the city. The location is very central, about 5 minutes' walk from the Osmanbey metro and the shops and restaurants of Nisantasi, and about 20 minutes to Taksim. The flat itself is lovely and comfortable and has everything you could need, and Gizem herself is a wonderful person and very responsive. I had a small problem with the combination heater during my stay, and Gizem had it fixed in a day. I highly recommend Gizem and her apartment!
