My husband and I stayed at Nuria's apartment for 6 weeks while I was working in Valencia, and it was a great apartment--just as pretty as in the photos, and you can see the Torres del Quart from the apartment. There was plenty of space, even for a trip that long (we even had a friend staying with us for a while, and it was fine for three). The kitchen is well supplied with equipment, and everything works well. Nuria was a lovely and very attentive host.
The location was also perfect for us. It's out of the tourist zone, so a bit quieter, more locals, and lower prices, but in five minutes you're in the center. The bar across the street, Piko's, is a lovely typical Valencian place for coffee or drinks or tapas, and a few doors down La Vianda sells delicious paella (and wine) to take away. If you're looking for a more authentic experience, but still convenient to all the sights, this is a great option.
