I made an inquiry regarding dates when reservations are not allowed. They answered me quickly and well but they could not guarantee the reservation for the days I needed. I had to secure them elsewhere.

Las Cigüeñas Motorhome Area, Madrid.

It's fine to spend a night, change deposits and be safe. The metro is far away, but we took a Bolt for €10-12 to the center of Madrid. The floor is Chinese, there is only one bathroom and one shower, fair cleaning.

It is in a polygon, a very quiet area and continuously guarded. There is a supermarket nearby.
The man who received us correct. The reservation through the platform is quick and easy.
Everything's fine.

All perfect!!
