I stayed in 4 places while in Istanbul. Ruhi's was my favorite by far. Best area of town and fantastic value. It's close to the kind of grocery store / supermarket common to the Western world, but hard (at least for me) to find in Istanbul. His internet works well and is very stable. His place is stylish, comfortable, and everything works. He's an organized guy and into healthy living. If you're lucky enough to come across this listing don't hesitate to claim it.
Ruhi also has a very handsome cat named Pandora. We had a great time together.
