We had really enjoyed our stay in Istanbul. Apartment is very charming, furnished with a good taste and oriental style.View from terrace is really great and it's a perfect place for coffee.
Also location is convenient, we like to walk so we didn't need any transport to reach the old town. Mustafa and his brother were very friendly. Their english is basic, but they managed to explain us everything, and they were always around if we needed anything.
Thank you Giusseppe and Mustafa :)
