No problem at all... i actually saw another one yesterday... It's called La Dalia and it's on Calle Pez. I don´t know the number, but the steret is not far from Gran Via. If you go from Gran Via to San Bernardo, and just walk on San Bernardo for a few mintues then you will fine Calle Pez, from there the store is like a 3 minute walk(tops). Anyhow, i don't think you'll have a problem. And hey, i go to that gym by the first store i told you about...soooooo, if i hear english there one day soon i'll say "SpainSpud? is that you??"
Cheers,
Rhonda
