Our stay at Almudena's place was great! She accomodated our very late check in for a small fee, and check in was super smooth. The apartment is cute and clean, everything was functional, and her guidebook explained the appliances and things clearly for anyone (like us Americans) that they might be a bit different for. The location couldn't be better. The Reina Sofia was 5 minutes away walking and the Thyssen and Prado only a bit farther, and Atocha train station is only about 10 minutes. We actually only used transport other than walking one time. There are amazing restaurants right downstairs and right around the corner - we really loved Oliveto in particular, and Anton Martin market is a few minutes away. The only suggestion I'd make would be adding an automatic Nespresso machine or something similar, or a larger Moka pot. It was a lovely stay and we appreciated having such a great home base to explore Madrid!
