I had a great month-long stay at Jimena's place. My room was comfortable, and the common areas were well-equipped and always clean. The location is unbeatable - there is a metro stop one block away, a few great restaurants on the same block as the building (highly recommend India Mandala!), Wal-Mart is a 12 min walk away, it is a 10 min walk to a strip of restaurants and bars in Condesa, and a 5 minute walk to Chapultepec. The staff is very hospitable and helpful - they were my favorite part of my stay. Highly recommed if you're staying in Mexico City for a while and need a comfortable place that is close to everything!
