Fran & Almudena are very friendly hosts.
When we arrived, Fran gave us the key and showed us the room. The flat is perfect for a weekend trip for 2 persons. It is near the historic center and you can reach the beach in round about 20 minutes by bike. He also gave us a city map and showed us some places on the map.
You can ask him everything you need. He gave us some hints for vegetarian restaurants and where you can rent bikes for a cheep price to visit the best places like Albufera de Valencia (you have to see the sunset there, perfect to achieve by bike)
We totally recommend this Airbnb :-)
