Guillermo's loft is a truly wonderful place to stay in Mexico City. It's in a quiet area of Hipodromo / Condesa, but very close to the heart of everything. The loft is on the second floor, with a lovely view of the neighborhood. The space has been impeccably designed, and the balcony is especially wonderful. Perfect for reading, meditating, practicing yoga, hanging with a friend.
Guillermo was a great host, providing many helpful recommendations—and answers to all my questions.
Just one note for those with a fear of heights: this may not be the place for you, as you must climb stairs. Didn't bother me at all—it gets you to the wonderful balcony and view.
