Guillermo's place was a good value for Madrid. The location is convenient, as it is located between two popular areas: where the Prado & Thyssen museums are, and where the Royal Palace is. It is also near a lot of restaurants and night life. Guillermo is awesome and one of the best people I've met in Spain. Interacting with him and his wife was a pleasure. The room is in the interior of the building with little ventilation. This was inconvenient in the Madrid summer heat. A fan in the room would have helped a lot. Other than that, I had a good 2 days in Madrid, Guillermo is cool, place is a good value, and the location allowed me good access to all the places I wanted to go to in Madrid.
