For those of us who love poking around the city and finding an open door to one of the many hidden worlds found all over town, there is a real gem at the Casa Universitaria del Libro in Colonia Roma. The house, built in the 1920's, was a private mansion of a wealthy couple, later the Embassy of Brasil, the Centro Asturiano, and how is part of the UNAM, whose guardianship of old buildings in Mexico City continues to expand. The lovingly restored interior is one of the finest you will find in Roma--a brief glimpse of the glamorous life of yesteryear.
Classes, expositions, and other book-related events take place here. The address is Orizaba 124, at the corner of Puebla.
