The real reason to stay here is the location. The apartment is on a street loaded with outdoor cafes and tapas bars. The Prado, Reina Sofia, Palace, Plaza Mayor, Puerto del Sol, Casa Lope de Vega, and Thyssen are all within a mile of the apartment. You won't find a better location in Madrid - really. The apartment itself is on the 5th floor and slightly cramped. There's no elevator. There are three small bedrooms, will two double beds and a couch that converts into a double bed. There is a washing machine, small kitchen, and hair dryer provided. My wife and I struggled to get good phone reception on our way to Madrid so couldn't contact the hosts in a timely fashion to let them know that our check-in time was changing, but they were very gracious in dealing with our late notice. I'd stay here again happily.
