Nurhan's place is a perfect option for staying in the Ortakoy Besiktas area.
It's a spacious flat with all the needed appliances and amenities. The apartment is situated on the top level, which provides you with a comfortable sleeping without bothering by upstairs neighbors. The neighborhood is full of facilities, including a big supermarket, taxi and bus stop, shops and cafes.
Nurhan is an exceptionally responsive and hospitable host I can highly recommend.
