The apartment is lovely -- on a quiet side street in a the Roma neighborhood. It's near parks, galleries, and great restaurants and bars.
The apartment looks on to a garden, and it has its own small outdoor space. It looks just like the photos, but the layout is better in person. There were nice touches like fresh flowers, a snack, and water when I checked in.
María was responsive to contact via email. I enjoyed my stay very much and would love to come back.
