We stayed at Barbaros place for 6 days. The apartment was great: clean, spacious, warm and well-located. Maybe the only trouble was that we had to go up the hill, but the street was great and we really enjoyed our way to all the main attractions and sights of Istanbul. By the way, the tram station Beyazit is the nearest to the apartment. You also have to take into account tha the street can be a bit noisy, especially on Friday nights, as there are lots of restaurants with live music. What else? Barbaros is a supernice host. He has his own restaurant with the most delicious fish soup ever! The only trouble we had was the smell of smoke, but Barbaros did everything to eliminate this slight inconvenience. And his advice was of use for us! Istanbul is great, enjoy every minute in there and stay at Barbaros!
