We enjoyed our stay very much. The apartment was bigger than we had expected from the pictures. The location is excellent - central, but quiet, and with good restaurants very close by. There are two Metro stations nearby - Colon, about a minute away, and Alonso Martinez about 5 minutes away, but we were able to walk easily to many of the main sightseeing places - the Prado, the Thyssen-Bornemisza, the botanical gardens and the Retiro are all about a twenty-minute walk away, through some great architecture. The hosts are very easy to communicate with.
