We had a very good experience in the apartment. It's located in a very authentic neighborhood and there are very nice cafés on the way to the bus station. We didn't met Giuseppe but Mustafa and Ugur helped us with everything, they were very helpful und friendly. We just had the feeling that the place is actually smaller than it looks in the pictures, but in Istanbul you actually don't spend a lot of time "at home". The rooftop is very nice, we will come back when it doesn't rain :)
