We stayed in Room Mate Mario, Madrid, for four nights in November 2012. I'd picked the hotel on the basis of other reviews. This is a stylish hotel in an old building and despite being there for several days we had to follow the signs to find the breakfast room. There are lots of jogs and small flights of stairs. The breakfast buffet was great--open until noon daily. I loved the location, steps to the Royal Palace and, better yet, to the Opera House where we attended a chamber orchestra concert (great seats for 8 Euros and less expensive than a tour) and two one-act operas (one event). After orienting ourselves to Madrid on a Hop-on Hop-Off bus (tickets purchased at the hotel), we found we could easily walk to the Plaza Mayor, the Plaza del Sol, and the Prado.
