A great place in a quiet neighborhood -- a little off the beaten path, but still close to everything. Only a 20 minute walk to Avenida Amsterdam, and just 10 minutes or so to Chapultepec Park (use the entrance hidden between the flower vendors on Constituyentes).
Great amenities: a very comfortable bed in the master bedroom, a fully equipped kitchen, and comfortable places to lounge around. Plus Santiago and Gabriela are very attentive and communicative. All in all, a great place to stay in Mexico City -- check it out.
