You should definitely stay at this airbnb. Its location is perfect with close walking distance to most main sites in the city (blue mosque, hagia sophia, grand bazaar, etc...). The room is extremely clean and looks exactly as shown in the pictures. Barbaros owns a restaurant next door as well and the food is very good. He is also very generous with discounted meals as a perk of being a guest. I also enjoyed my conversations with Barbaros and his friends as it gave me a better understanding of Turkish culture. I will absolutely stay here again if I'm ever in Istanbul again.
