Highly recommended. Duygu and her friends were wonderful and the apartment is a gem. The apartment has all the amenities and Duygu kindly left some important toiletries and food items. The apartment is also really well located--close to sites in Beyoglu, lots of cafes, restaurants, and shops (including grocery stores), and public transportation (subway, tram to Sultanahmet, ferry). My flight arrived later than I initially thought and Duygu very kindly accommodated the change. Upon request, she also provided a plug-in mosquito repeller. Would definitely stay here again.
