We really enjoyed the stay at Billur's lovely apartment. Great location to explore the trendy cafes and restaurants of Nişantaşı (2-3 minutes by foot), but at the same time close to the MRT/Metro station Osmanbey. You can also walk to Beşiktaş (20-30 minutes) where the ferries leave for the Asian side of Istanbul. The apartment is cozy, with a large living room, nice bedroom, fully equipped kitchen and an extra room (that we used for our luggage). The host is very friendly and responsive.
