Ilayda's place was absolutely wonderful. It was our first day in Istanbul and staying at her place in Kadıköy made our time in Istanbul all the more wonderful. Her apartment is clean, spacious, easy to find, and very close to the ferry station and bus station.
Ilayda herself was super friendly and accommodating. My mother and I really enjoyed our conversations with her and we were sad that we only had 2 days at her place.
If you are looking for a place to stay that is close to major sights, but not so touristy and want an authentic Istanbul experience, stay at Ilayda's place.
