inexpensive places to stay in Madrid?

There is a lot of very good budget accommodation in Madrid. My own favorite is the Hostal Bruna,which is very close to the Paseo del Prado and about a 4 minute walk to the museum. It is small, family run, extremely clean and BASIC. http://www.ctv.es/hostalbruna/indexin.htm

It is very near a lively entertainment area, good restaurants, lots of night life, but I've always had a room with an interior window and it's silent at night.

I always try to plug this place when I can because they treated my 24 year old son so very decently about a year ago. The night before his return to the US he was pickpocketed. He didn't realize it till the next morning when he went to pay his bill and head to the airport for his flight home. These guys not only calmed him down and told him not to worry about the bill but to send them the money when he got home, but they also gave him money for his trip to the airport.
