I have been there. It is a typical buenos aires province town with a nice city centre. There are quite a few craft shops. Also, nearby is the lagoon (Laguna de Lobos) very popular with fishermen. It's an ok place to spend a day or two to relax. I agree that there are quite nice estancias nearby. I highly recommend Estancia La Candelaria http://www.estanciacandelaria.com.
