Mmmmm, you are right. I put "only" because I copied an existing station.
I did it in several places, I'll try to fix it.

I'm not sure if this can be considered an ambulance_station. It's more a lifeguard_base, right?

Thanks, looks like I copied the format of other node :-)

Debería renombrarse a Monte de El Pardo

I've asked him in the changeset
osm.org/changeset/30014224

Buenas,
En este conjunto de cambios subiste un montón de piscinas, quizá desde una importación. ¿Tienes forma de saber cuales de ellas son estrictamente privadas para indicarlo?
¡Gracias!

OK, I'll do it and I'll also review the changeset myself. For example, the second of your nodes seems to be public. The changeset is named "piscines privades i publiques" meaning "public and private swimming pools" (in Catalan)

I need you to be more specific, that's a huge changeset

a qué fallos concretos te refieres?
