We had a great stay at Melek's place!
The room is clean, bright and well decorated. Melek is really welcoming and made sure we were not missing anything. They offered us to help ourselves to breakfast, tea and coffee and made us feel at home :).
The place itself is situated 5mn away from Warwick Avenue where the Bakerloo line is, so you are literally 18mn away from the center by metro.
Hoping to come back :)!
