Ugur was a great host. I forgot my bag in the taxi when I arrived, and he talked to the authorities and got the situation solved in a matter of minutes, and the bag was back. His friends in the building are very nice as well but they don't speak English.
The neighborhood is historical and beautiful, and wandering around is a nice experience itself. But be ready for some tiring walks as the building is on the top of a hill with steep streets.
The building itself and the apartments are not fancy at all, but it's a good value for money. And the location is perfect as all Istanbul's attraction are easily accessible from there.
It was a nice experience, and when I recommend it to anyone planning to visit Istanbul.
