We stayed here in a matrimonial room for one night in Aug 07. Included in the cost is breakfast as well as transfers to/from the hostal.
The room is very small and very very basic. The bathroom is tiny and of a reasonable standard of cleanliness. Breakfast is provided as apart of the cost ie bread rolls, coffee/tea. Staff were friendly though spoke minimal English and unfortunately I speak bad Spanish!
The location is quiet and close to all amenities and attractions in La Paz. The price you pay for this hostal is comensurate with the standard and service and is okay for one or two nights.
