The apartment was beautiful. We stayed there for 4 nights in May.
Javier met us on the day and he was amazingly helpful. He told us all the good restaurants to go to (and which ones to avoid). He even gave us a lift to the supermarket and picked us up afterwards!
The apartment had absolutely everything you could possibly need. Bathroom was modern and the shower was great. Best of all was the large terrace outside - great for breakfast in the mornings and relaxing while your girlfriend gets ready!
The beach is so close it literally takes only two minutes to walk to it. We had a small issue with a little bit of noise from a nearby club one night but we're assured that's getting sorted out.
If I was in Valencia again I would definitely stay at Javier's apartment.
(Another thing - my girlfriend left her dress in the apartment and he posted it back for her - no charge!)
Thanks Javier.
