Carlos' apartment was absolutely beautiful in the heart of Madrid! It was exactly what we were looking for! One plus was the ample hot water for 9 people! Carlos was very easy to work with as was his housekeeper who left us into the apartment. The air conditioning only reached into the common areas and not the two bedrooms; however, the hot summer day cooled off and there was a more than ample breeze with the windows open. The noise from the street could be an issue for some but for us it was no problem.
