This is a very charming property, just 5 rooms or so, a very special atmosphere. It's well kept, and the rooms have nice private bathrooms. Fernando, the proprietor, is friendly and interested in arts and literature, and runs a lovely bookshop-cafe in the front room and courtyard. It's a superb location -- in central Guanajuato but on a quiet street.
Just a couple of shortcomings. Because the rooms' windows open onto the Zaguan (the covered courtyard-patio-cafe) rather than to the outside, you are likely to keep the curtains pulled closed. Though there are lots of restaurants nearby, there is no coffee available onsite until the cafe opens at around 10:30 a.m. Our room also lacked a chair and reading light.
