Airnaldo was a great host! He was quick to respond to all messages. The apartment is small with thoughtful touches and decor; it is all one needs if staying in Madrid for a few days. The bathroom and shower were great! The location was convenient; across the street from the train station and Reina Sofia. It was about a 10 min walk to Park Retiro and Prado Museum. Plenty of restaurants and bars near by. Only thing to note - if you’re a light sleeper the street outside does stay somewhat noisy at night with cars driving by and people walking by (comes with being across the street from a major transportation hub). I would stay here again.
