Great apartment right in the center of Galata (and that's exactly where you want to be). The interior is spacious by Istanbul standards and very comfortable for remote work. We really enjoyed our stay! The only issue is the smell that occasionally comes out of the bathroom, but you can just close the door and forget about it.
Savaş is a very considerate host who helped us with any questions we had and replied really fast. For that we are very grateful!
