I am not sure what to praise more. Carlos' place, the location or what a great host Carlos was. The flat is big and contains everything that you need for a great stay. I don't think the description of the apartment indicates well enough how well equipped the apartment is. The kitchen has everything that is needed. There are facilities to wash and dry clothes, and there are also stuff for the beach. The apartment is big and beautifully decorated.
If you go to Valencia for the beach, Carlos' flat is perfect. It is about 5 min walk from the beach. The tram stop is nearby, so getting to the centre is easy as well.
Carlos was a great host. He welcomed us when we arrived and helped us familiarise with the apartment. He recommended us several places where we can eat and buy things, and he was always available if we had questions.
