Jacobo's flat is outstanding and so much nicer than what the pictures let on. Its location is unbeatable (near the city centre, across the road from the Turia River Gardens, and more) and the owner, Jacobo, is an outstanding host.
A good part of why our trip to Valencia was such a pleasure (what a lovely city!) was Jacobo's place.
I cannot recommend Jacobo's place enough. If you don't book it, you'll be missing out.
