Alex is a wonderful and attentive host, with great precise directions and local recommendations! The apt is exactly as described (modern and spotless) and is in a great area in walking distance of a fabulous cultural park (15-20 minutes to El Bosque Chapultepec), and a major avenue with dynamite rooftop restaurants. The neighbourhood is super safe.
I was really grateful that I found Alex and his place because my first trip to Mexico City was all the more amazing. Highly recommend! Thanks Alex!
