This is an unusual apartment for Mexico City generally, and Polanco specifically. It is in a superb, quiet location, on the 3rd floor, looking out on one of the most densely wooded squares (actually a roundabout) in Polanco. I notice the blossoms on the trees attracted hummingbirds just outside the windows. The open floor plan is exceptionally inviting, and has a wonderful feeling of spaciousness and light, not least because the windows extend fully along two sides of the room. Diego's library is astonishing in its breadth and interest - politics, history, literature, philosophy, photography and more. You could spend a month just browsing and reading his collection. My guess is 2/3 in English, 1/3 in Spanish.
This apartment is perhaps best suited for a tidy person who is looking for a very serene workspace - the desk area has plenty of room to spread out - or a couple who want a convenient base of operations for accessing Polanco's posh dining and shopping options, while being close to the park and museums.
