I'd like to mention to everyone here that the El Prado Apartment in Huertas has recently changed their OFFICIAL website URL to http://www.telefonica.net/web2/madridrent/ . Tomorrow, I'll update that link on my Madrid Apartments page .

Maybe that's the reason why you never heard from then. On this new page they list a new email address.

Good luck on your search! Saludos, MadridMan
