We really enjoyed staying at Micks'. The flat was clean, nicely furnished and in a great neighborhood with lots of restaurants and bars. Victor (a friend of Mick) was extremely kind, gave us some good tips were to go and how to get around in Valencia and recommended a pretty nice restaurant.
We only used bus/metro for our way to the airport, everything else is in walking distance or easily accessible by bike (bike rental directly in neighborhood).
We would definitely recommend staying at Micks!
