Stay
Renting a villa or apartment
The real Jávea feeling is a house with its own pool among the pines, and the choice is enormous: many thousands of villas and apartments. Book through a platform with genuine guest reviews and pay close attention to the distance to the sea, because from the hills you end up driving everywhere.
If you would rather book with a local rental agency, pick one with recent, verifiable reviews and a clear contract. The big local names are not all equally consistent in their service.
