I just came from Madrid, after staying a few days in the Hostal Dominguez, in Malasaña. By far, my worst travel experience in many years. I normally follow the recommendation of a travel guide whose info is in general very accurate, but in this case... Not only the place is decaying rapidly after the renovations, but the owners seems to be tired of their job, and treating the people accordingly.
Try any other place, believe me, there are hundreds in Madrid...
