Ayşen is a very communicative, responsive, and helpful host! We arrived a bit earlier than the check-in time but she had no hesitation to welcome us at the entrance of the apartment and to carry our luggages upstairs.
The flat has the perfect location at the heart of Kadıköy. It has everything you may need nearby: public transportation, supermarket, pubs, cafes, etc. The flat also has everything you need, from washing machine to kitchen utensils, towels, bed sheets. The only thing that could be improved is how clean the flat looks, but I think that comes from the fact that the building is very old. But this is quite normal for flats in the same neighborhood and around the center of Kadıköy. We stayed 2 nights and overall, we had a very pleasant stay.
