My experience in Nadira's flat was definitely excellent! The flat is located almost next to Galata Tower (European side of Istanbul - district of Beyoglu), and such a location is perfect to move almost everywhere in the centre of the city (lots of bars and clubs all around Galata Tower, and along Istiklal Caddesi; Sultanahmet area, where most of historical attractions are; Eminonu port, where you can take the boat towards the Asian side of the city). The flat was clean and really confortable, but the only weak point is that it's on the 5th floor of the building, without any elevator (it could be a problem if you carry heavy luggage or for people having mobility problems). Otherwise, it could be also a good training session every morning before your long walks in this enchanting city (strongly recommended).
