My stay was just lovely! The apartment offered everything I needed and felt like a real home. But especially the area and the neighbors were awesome, as well as my flatmates. You feel that Selen wants quality in her apartment and picks the people you will live with wisely. The place is very noicy. For me personally this was no problem at all- but this information is maybe useful for future guests.
All in all I just had a beautiful time in Istanbul and would highly recommend Selens apartement:)
