We stayed as a family: two adults and two kids. The stay was good and communication with the host was nice. The apartment are nicely located and have two bedrooms although one has only a single bed. The apartment are rather basic: not very comfortable mattresses, no shampoo, lack of light in the leaving room (easy to fix like lamp bubbles). My wife noticed a light strange smell in the apartment.
Juanlu is a very nice person and responds quickly. We were asked for ids and I sent mine as he had to fill out some tourist forms. I think this should be omitted and handled through airbnb; never happened in Spain to us.
