Borja's apartment was great for a one-night stop-over in Madrid before traveling elsewhere in Spain. It's very close to the metro and made for easy connections: it's about an hour ride on the metro (with a couple line changes) from the airport, and only about 20 minutes to Atocha station. The self check-in and check-out was convenient and easy. It seems that the walls in the building are rather thin -- we heard a neighbor come in around 4 in the morning, which woke us up -- but it wasn't a major issue. Contrary to the description at the time of our stay, there actually *was* an elevator, which made it much easier to handle our baggage. The apartment shows some signs of wear, like many scuff marks on the white walls and some small finishes that could use improving, but overall it was a cute and convenient place to stay in Madrid!
