A great location in a buzzing neighbourhood, but nice and quiet at night. Walkable to the Plaza Mayor and other areas of interest in central Madrid, with all amenities (cafes, supermarket, bank ATMs, Metro, etc.) on the doorstep. The Rastro on Sunday starts 20 meters away at the bottom of the street.
A good hike up the stairs to the apartment, and the beds were quite hard, but the flat was well equipped and reasonably spacious, as per the photos, but mind your head on the beams! We had an issue with the AC turning off on the first evening, so spent a sweaty first night before this was resolved by turning the fuses off and on again, as per instructions received by text.
Recommended for a few days discovering Madrid's amazing sights.
