Good location (near Atocha train station, Reina Sofía museum, and Retiro Park). Many metro stations nearby too.
Dishwasher did not work during our stay (owner was quick to respond and try to repair it). Hopefully something that can be solved soon.
Cleanliness was ok for me (not so ok for my wife that has much higher standards). It must be noted that we were allowed to check in a few hours before the official check-in time, which maybe rushed the cleaning a bit.
Overall, a fine place to stay.
