We had a great stay at Ertuğrul's place. A clean, trendy and cosy place right in the centre of Besiktas. The apartment is above a cafe and every morning you can smell the delicious chocolate pastries. please note that you are in one of Istanbul's coolest and liveliest neighbourhoods so there are lots of cafes and bars around. To keep in mind if you are an early sleeper. it gets quiet after midnight though, so no issues on our end. Overall we are very happy!
