It doesn't get better, this is the place you're looking for.
I thought the other reviews were a bit over the top, but they're all true.
This place has it all: super clean and comfortable accommodation, lots of amenities, easy walk to the old town, and of course, the most gracious hostess, Elvira.
Staying here is the best way to experience Valencia. Yes, you need Spanish to communicate, but you *are* in Spain, and Elvira's patience even got us through my limited, broken Spanish.
Go for it!
