We loved the place! It looks exactly as in the photos, has everything you need for a comfortable living and is close to Istiklal, numerous restaurants and cafes yet quiet. Guner is indeed a super host as well as his team, quick at response, very cooperative and helpful.
The only minor issue We had was the wifi sometimes slows down, but again Guner’s team were quick to respond and fix it. If I ever visit Istanbul again, I would definitely book at Guner’s.
