Fabulous location, 5-10 minutes from the Atocha Train station and walking distance to all of the main attractions: Prado and all of the other museums, Retiro Park. There is a small market at bottom of the stairs, which we used several times.
Apartment was spotless. Beds were comfortable.
Check in was fast and friendly.
The only thing that could be improved is getting two sets of keys for a group of 5 from the beginning.
Generally a great stay.
Thank you
