We were a family of 7 who stayed at Erdem's Airbnb. We enjoyed our stay very much. The flat was comfortable and modern. Location was great (though if staying with elderly relatives steep hills may be a bit tricky but not too bad!) with lots of shops and restaurants near by.
All the utensils available in the Kitchen was great for us as a family, so we can make breakfast and tea/coffee to our liking.
Erdem and his team were very responsive and helpful, going above and beyond to respond to our queries.
Should we return to Istanbul, we would be sure to stay here again!
