Julia and her husband are great hosts. They were very helpful with everything. For example we arrived very late and her husband was waiting for us in the apartment and helped us with parking (which is quite an issue in Valencia). The apartment is huge. There is everything you need for a couple of days. Very helpful for us were the map and the tour guide in the apartment. The location is perfect - very close to center and City of Science and in the same time very quiet. It's very suitable for families.
We would definitely recommend it!
