We had a really great stay at Ayse's and we recommend the place. She's an amazing host, very sweet and always willing to help. Communication was great, she replies right away and is prompt to resolve any issues. Regarding the flat, it was clean and large, with everything you might need. The flat is located in a central yet calm area, it's like a residence. If we come back to Istanbul, we will definitely consider booking at her place again! It felt like staying at a friend's :)
