Both Yusuf and his place are great! I would recommend staying here to anyone coming to istanbul for the first time who don't have very many freinds to learn about what all to do from. He helped us find a local clinic when one of us had an ear infection and arranged a private shuttle for us which was much appreciated. The room itself is cozy and more than enough for anyone spending a few nights mostly out in the city. He also provides lots of recommendations for what all to try and where to visit.
