How did you manage to take such a long vacation? I usually plan for a seven-day vacation, accounting for travel time. I usually use the service https://gettransfer.com/en/directions/spain when I travel. You can book the necessary dates and transfers in advance on their website. The car always arrives on time. Personally, I like the beach at Passeig Maritim de la Patacona. I also recommend bar "The Jungle" and "Bar La Terraza". Let me know what you liked most because I'm planning to visit Valencia in October and want to explore new places.
