Great place in the heart of Madrid. Easy access to both Sol and Atocha metro stations. Numerous bars and restaurants in the area - all of which were wonderful! Very close to both the Prado and Reina Sofia museums, not to mention the beautiful El Retiro Park. Honestly couldn't ask for a better location.
The accommodation had everything you could need - kitchen equipment, super comfortable bed, hot shower, TV, AC. It was also very quiet (I'm a very light sleeper!) as it doesn't overlook the main street.
Communication was also perfect. I arrived fully prepared and understood exactly how to access the building and the apartment. Truly nothing to fault.
