The apartment has a great location and a nice rooftop. And Furkan was nice enough to wait for us late at night when the plane was delayed. Other than that, the place needs cleaning (which we actually undertook in part, just for our own sake - we weren't sure the sheets were clean actually), no light in the hall or in the staircase (we bought new light bulbs but it still did not work) and there was no gas in the kitchen (which we asked for to Furkan but it just never happened).
So not very welcoming or very confortable either.
I would not advise it to other travelers, unless they absolutely have to stay in that street, are in big hurry and have no other choice left. Too expensive for what it is. Too bad, the apartment could be nice if taken care of.
