I stayed with my mother at Hakan's place for 5 nights. The apartment is beautiful - clean, spacious and well lit. Hakan had taken care of all the basics a traveler needs - the kitchen and bathroom were well equipped. And he was very helpful himself - he gave me his local Istanbulkart to use and carried my luggage up the steps. And was always available on phone. The only challenge is transportation in the area. And taxis are not easily available.
