La Casa Del Barrio
A hostel in the center of the Barrio Antiguo. It is away from most of the bars, but is still noisy windows of rooms face a loud courtyard, and it echos. Owner is often absent, so guests cannot get into rooms. Charge for use of stove, charge for breakfast, charge for laundry. Routinely overbooks, so you may not get your room of choice or any room at all. Beds vary in comfort levels.
budget lodging
Monterrey has a wide variety of options for the backpacker or extreme budget traveler. There are several very cheap hotels clustered within a few blocks of the bus station, though many feature dubious cleanliness. Hostels are a better option, and there are at least three hostels operating in Monterrey - these offer clean bunks for as cheap as US$10 per night. Several new budget hotels have opened in Monterrey since 2004: these new properties include a CityExpress on the southern side of the city, an Ibis in San Pedro, and another Ibis at the airport --- rooms can be had at all of these for under US$50 per night.
