Nice place, with a huge room plus attached balcony. Fantastic location in El Carmen, with street art from some of the most famous Valencian artists on the street the flat is on.
Everything worked, including the WiFi (50mbps) and shower (may sound surprising but not all of them do, at least not in my experience). The only slight comment is to beware of the clingy shower curtain. I didn't realise I was so magnetic!
José Patricio is an amicable host, and nothing is too much trouble, you just have to ask or let him know.
Would stay again.
