Nothing but compliments to the place and the host.
First of all, great location. Second, the apartment is cozy, quiet, and has everything. Has anyone mentioned the bed? Yeah, the bed is super comfy. The room itself might be pretty small but still, comfortable.
And the most important part - the host. One of the most welcoming and thoughtful hosts I've ever met; Orhan goes out of his way to help his guests, and I appreciate it a lot. So if you need a room and a friend in İstanbul, this is the place to go.
