Idil was the perfect host, replying to emails very quickly before our stay and providing us with lots of recommendations beforehand. She was at the apartment to welcome us when we arrived late at night from the airport and explained well how everything works in the apartment.
The apartment is lovely, clean and spacious with lots of interesting touches, and the location is great for seeing the sights both on that side and on the other side of the river at Sultanhamet. There are plenty of great restaurants, bars etc in the area.
If/when I go back to Istanbul I'll definitely look to stay at Idil's apartment again.
