We were very happy with Mersin's apartment. It is very clean and exactly as pictured in the listing. Very spacious, everything we needed and more in the kitchen, excellent wifi, and we very much appareciated having a washing machine. The location is excellent - a three minute walk to Tophane tram station on the T1 line which gets you to Sultanahmet and other convenient locations. There were great cafés a 10 minute walk away in Cihangir. Key exchange worked very well. Mersin's assistant met us at the apartment at about 10pm after our flight was delayed. The only drawback in our view, which others might not see as a drawback, was lack of interaction with the host. Mersin checked in frequently via this website and I always felt he was totally available for questions. However, we did not meet in person. Compared to other Airbnb apartments, i missed having a local contact who gives recommendations of places nearby, etc. Overall, highly recommend this apartment.
