Me and my parents spent 9 days in Gulnur’s apartment and we a great stay. The flat is spacious and clean, with a superb view south to the Princes Islands just as in the pictures. It’s ideally located 10 mins walk from the Blue Mosque/Agia Sofia and Grand Bazaar but is on a quiet street, and there are lots of little shops for groceries just outside the apartment door. The sofa bed is really comfortable, and did fine for me for 9 nights, so you really can host 4-5 people in the flat comfortably. All the amenities work well. The only exception I would give is the wifi which is pretty patchy and needed some rebooting, so maybe not the best apartment to work from remotely, but if you’re out most of the day and evenings like we were then this won’t affect you too much.
Gulnur was a great host. He left very clear instructions about all aspects of the flat and was on hand by email and phone to answer any questions we had. Would certainly stay here again without hesitation.
