You could show up with a change of clothes and be ok....there was a coffee cake, a loaf of organic bread, orange juice, milk, coffee and fine chocolates waiting when we arrived. The host is available and quick to respond. He thought of everything and I mean everything. Entry was easy, the building was safe and only 5 min walk to the train station, metro and closer for the bus. You can rent a car at the train station as well. Overall, I can't think of a better place to stay to act as a home base for exploring all of Spain.
