Cerith has been great during my trip, he came to my bus to help to find his flat. He shown me some nice places. He knows a lot about turkish history and art. His english is perfect and we even talked in spanish and french.
The flat is very central, it's very clean, the bed is very confortable and there is no noise in the building, so I could rest and sleep very well.
Cerith was ready to talk or show me the city when I wanted and was leaving me alone when I wanted to rest or do things alone.
I recommand him highly!
