We spend a week in February in Juan Luis apartment. Enough space for a family of 3 persons but not too big. We didn't had the chance to meet Juan in person, but we had the keys handed from Cecile, the cleaning lady as we could drop our luggage in a few hours early (very useful).
The apartment is located in walking distance (20-25 minutes) to Aquarium, Science Museum and Hemispheric.
Neighborhood is lively but you hear almost nothing on the 8th floor. Unfortunately, the family that lives on the same side had a small child and sometimes we could hear him crying during the night (not always). No big issues for us.
The rooftop terrace is spacious, however in February doesn't get too much sun as the apartment is North faced so we couldn't use it enough. Perhaps is great in the summer!
It was very easy to communicate with Juan Luis and he told us about many nice restaurants and advice on things to do in Valencia.
Overall, we had an excellent stay.
Thanks you so much for your great service, your many advises, tips and information.
