Orange studio was the perfect place to spend a lengthy stay in Istanbul. We had privacy in the small but functional space and the roof terrace is huge with nice views of Sisli. Fatih was helpful came and met us nearby showed us helpful maps etc. he also stopped in a couple times to see how we were going.
Sisli is a great spot out of the main tourist district but still close enough to walk to Taksim in 15 minutes and Beyoglu only 2 train stops.
We enjoyed our stay, Istanbul is amazing and Orange studio suited us sweet.
