Lodging at Martha's (15 blocks from Paseo de la Reforma, Mexico) was very much as described, and I felt welcome. A positive experience really. The neighbourhood is somewhat on the wild side, but I did never feel threatened. The market nearby was very good if in need for something, or just for looking at exotic foods. I can recommend Martha's to anybody who needs accommodation mostly for sleeping; of course, if you want a swimming pool, gym and restaurant, you may need to look somewhere else.
