If you stay in Valencia, definitely stay in Ruzafa. The apartment is in a great location and super well-equipped (including washing liquid and those sorts of bits and bobs, which is very nice), quick and nice communication. However, we were there in February and the apartment was a little cold and difficult to heat up. Also, the apartment is on the ground floor and got a little noisey at the weekend. However, that was only in the living room; we couldn't hear any noise in the bedroom.
