Very good location - close to everything. A lot of tabernas on Cava Baja street. You can walk on foot to the Prado museum or to Atocha train station for the trip to Toledo.
Comfortable bed. There is a heater in the apartment, so there was comfortably warm even in January. Hosts Tomás and Andrea responded very quickly to all requests. Overall, its an amazing place to stay. Just one small thing - an extra charge of 25 euro for the late check-in. It's not a big deal, but it would be nice to know before booking.
