Volkan was nice and easy to reach at all times. The house is like in the pictures, new and clean, it is an old building but he did a fine work renovating it.
I didn't walk much on this neighbourhood since I didn't have a lot of days. It was noisy for me in the living room, sometimes we couldn't open the window all the way but I guess this is Istambul, like my country Spain, noisy. The room was quiet, so good for sleeping.
There are two things that I wasn't very comfortable with, one being the bathroom, I didn't realized in the pictures that it was so small, the shower was very good but you have to take the toilet paper out every time you shower and there is no place really to leave your toiletries, and the second one was that we couldn't really cook because there was nothing to cook with, so it was not completely equipped, just basics. Not a big problem since there are a lot of restaurants to try out!
The stairs to the flat are very narrow and a bit steep so if you have trouble climbing stairs keep this in mind, other than that, you get use to it easily, Volkan helped us with our heavy luggage.
I must say that we are on our 40's and that is why I think this is a flat more for young people than for a mature couple. But it was all right for 3 nights and for the price.
