Very nice apartment with lots of light and very well decorated. Comfortable beds, lots of closet space. Great kitchen. It is located on a small dead end street that is well illuminated. Calle Hamburgo, unfortunately, is not a very nice street. The apartment is sufficiently close to Paseo La Reforma to overlook this minor issue.
Keep in mind that it's a 4 story building, which means you have to bring the luggage up yourself! Victor and Sergio and great hosts, easy to get in touch with. The building smells a little funky but you will find that a lot of places in Mexico have sewage issues.
