We had a really good time in the city and its outskirks (la Albufera, el oceanografic, the beaches and the old city center and... shoping!).
The appartment is ideally located at a 5min walk from the city center; very clean, quiet, nicely furnished and very confy.
Javier warmly welcomed us, with pieces of advice on the places worth a visit, and made us feel confortable with the flat (bedrooms, kitchen, smooth towels, etc...), and offered a local champagne!
This is definively a place that I recommand for an enjoyable stay in Valencia.
Thank you Javier for everything!
