I highly recommend Roda&Chiko’s place. The location is fantastic between the Galata tower and the famous Istiklal shopping pedestrian street (plus nearby museums, sites, hammams and waterfront). Despite this, it is not ‘touristy’ and is actually just next to the luthiers district (many small music instruments workshops and stores) and full of friendly locals, back streets with hidden delicious turkish cafes and restaurants and small boutiques. It’s 2 blocks from the Shishane metro which makes getting to the airport easy/affordable if you want to avoid taxi. This apartment has wonderful views over Istanbul /the Golden Horn from 4th floor and rooftop, a very comfortable bed and a little kitchenette and living room area. All very stylish and cozy. Most of all, Chiko is a kind, responsible and helpful host, communication with him was excellent from the beginning and it was a pleasure dealing with such a friendly local who gave me great tips for places to eat, how to use the metro and made me feel at home in his neighborhood.
