We stayed there last autumn. It has great facilities save for the water point already mentioned. You can also have a bit of a stroll to empty your toilet and grey water unless you are close to the disposal point.
You can "rent" a tap so as to use the water point at your pitch, I can't remember what this rental was, save that it was not cheap but probably worth it if staying for a while.
The train into Barcelona costs about 5 euro and the bus down to the station from the campsite is about 1.5 euro.
