Barbaros' airBnB was amazing- for its location closeby the main center- less than 10 minutes to the tram station and airport transfer station. I was greeted with a map of the city- he was very responsive and helpful throughout my stay! I would definitely stay there again- laundry and common area was useful and spacious too. If I could stay longer in Istanbul, it would definitely be at Barbaros' airBnB!
