Bonjour madame! Lonely Planet says of Hostal Chinchon that it is 'a pleasant place with an internal patio just off Plaza Mayor. Singles & doubles with own bath and TV cost 4000/6000 ptas + IVA.' Soooooooo, I found Hostal Chinchon's link to see if prices were in Euros (they're not):

as well as this one for another hostal:

I don't want to outdo myself (!!) but went on to find a list of Chinchon hostal links:

I'd really appreciate a review of your stay in Chinchon when you return. Plume
