a group of us are going to picos in 2 weeks time self catering apartments in potes if you e mail [email protected] and give her your requirements she will sort it all out for you .
Thanks triplet, since posting this request Petite Pillion has found and fallen in love with a gite in France so we are heading there instead. Sorry about that. Hopefully the link you posted will be of use to others.
Villa de Potes is a great self catering establishment just off main street in Piotes which is in the middle of the Picos de Europa http://www.villadepotes.com/
