Silvita, I've moved your topic here from its originally posted forum category of "Alojamiento" which is a Spanish-language-only forum category.
If you're looking for a simple room you could try http://www.VenAMiCasa.com
for a room in a family home. Otherwise, you can try the big national newspapers http://www.ElPais.es
in their classifieds sections (paper and online).
You can also scan through the past postings in the "Classifieds & Personals" forum category for people searching for roommates or who have apartments for rent.
Good luck! Saludos, MadridMan
for Barcelona information, Transportation, Lodging, & much MUCH more!
