Sorry to say that, but I was disappointed...
But good things first. I stayed there for 6 nights in June, 2017. Omer is a kind guy. He met us on the arrival and helped to arrange the taxi on departure. The location is really great - just in front of Galata tower , so you will never get lost!
The apartment (and I believe all the house) WAS really good and stylish FEW YEARS AGO . You can see that the owner invested in the property . There is everything you might need. But today it is really unkept and the lack of good maintenance is obvious. I might sound picky , but I am the host myself, so I know how it should be. It is pity to see how good property is falling apart ...
We stayed in the apartment No.7 . The old wooden floor (which i great idea) is broken right at the entrance to the bathroom , so you are falling in the hole every time when going in or out , silicone sealant from the gaps already falling out. My understanding of "clean" is far different from what we found in the kitchen...The door of the fridge does not fix , so we had to use chair for it :)
The linen of second blanket was obviously not fresh and surprise - dirty shirt, socks, underwear in the washing machine !
And finally - the roof terrace . It looks really different form the picture. The plants are dead , the mess (paper cups, cigarettes, sand) was never cleaned.
Despite that I liked Istanbul very much and will come back for sure ! But will stay in some other place ...
