Volkan's flat is calm, clean and well located (next to the very lively Istiklal avenue, great places to go out in the evening, 10 mn walk to the tramway and underground). We had everything we needed, it was warm in the flat although we travelled in winter, and we slept well. We were not welcomed by Volkan but by a friend of him, who was very nice and waited for us although we arrived later as expected. Communication was good. Would definitely recommand it for the price.
