Jose responded very quickly to my messages before we arrived and was very helpful, even although the airline changed the times of our flights more than once. He was very welcoming and told us all we needed to know. The apartment is just as described - bright, clean, and with fascinating decor. It's close enough to the old town to be within easy walking distance, but without being disturbed by the bells of the Cathedral. You can also walk easily to the Botanic Gardens, or a little further away, to the Bioparc.
I would recommend this apartment for a visit to Valencia.
