We had a short stay at Alper’s flat but it was very comfortable. He kindly accommodated us for an early check-in as we were arriving in Istanbul early on the day and had no place we could leave our luggage. Communication was excellent! Alper was very responsive and he helped us with all the questions that we had. The flat is in a great location with the metro, shops and restaurants all around in walking distance. It was very well equipped, quiet, clean and very homely. Would definitely recommend staying at his flat if you’re visiting Istanbul.
