Staying at Aydan's place was great. The room is spacious, there is everything you need and the bed is very comfortable.
Aydan is kind and helpful, so is her boyfriend when is around (who also has a very good English) and I felt welcomed and among friends all the time.
It is also very close to the transports such as Metro Bus, Marmaray and other bus stops, though you can get in the central areas in about 10/15 minutes walking. Also there are any kind of restaurant and street food shops just down the street, so that is also never a problem even for the days you don't want to go far.
I definitely recommend staying at Aydan's place and I'd surely stay again :)
