Ibis gives the important things -- strong and hot shower, firm but comfortable bed, quick and reliable wifi, great location -- at a sensible cost. Staff and management vary widely. In Ibis Mexico Alameda, the staff I encountered were generally exceptionally respectful and helpful. I would rate this group the most excellent of the numerous in a dozen countries I have stayed in. This location has the advantage of being close the historical centre, Chinatown, shopping, and a vast number of street stalls.
