From the article: Madrid Wikitravel-Style Travel Guide
Madrid is a big city - no-one can visit everything it has to offer. What would you suggest that visitors to Madrid do? What Do YOU Suggest?
Beware SIM Card
- I strongly suggest you do not purchase a SIm card in the Madrid airport from Exactta.(Latin American Enterprises) I had a great many problems dealing with this company as well as being charged an outrageous price for the card which did not work.
