Hola SpainSpud,
Ok the address of the store i have talked about is Calle San Leonardo #7. The street is perpendicular to C/ Princesa/Gran Via, directly across from Plaza de España. Soooooo.... i hope you find it, and it serves you well. I don't think you'll have a problem though.
Saludos,
Rhonda


It's right across the street from a gimnasio(gym).
