Şahin is a wonderful host. We had a lot of good talks and I found a friend in him. He is a very friendly, helpful and courteous guy but he gives you your space if you need it. I will be staying with him again, when I'm back in Istanbul. Şahins place was very cozy and conveniently close to the metro station Osmanbey. But there's also good places to eat and go nearby. All in all it's a five out of five stars if you want to travel Istanbul from a locals point of view!
