We stayed at Francisco Joses appartement for a weekend, to explore the beautiful city of valencia. He welcomed us and gave us the keys, he knew that we're germans, so he came with a german friend, so the communication was absolutely no problem. They showed us everything in the appartement (which was super great and really clean) and also gave us some tipps where to get the best paella in the city and where to enjoy the nightlife. He was a really kind host, and I can recommend the appartement to everyone. Everything you need is there, and there is enough space for 6 adults.
It's a bit far from the city center and beach, but we rented bikes for 6 Euros/ day in the city so it wasn't a problem anymore.
