I like the Kepeniski hotels. The Park Chateau is my fave, followed by the Park Central down the street. Both are in Ricoletta and can be booked for a reasonable price on expedia. I have ususally paid about $100-$125 Canadian per night. Ricoletta is a nice area, but you must get out and about in BA. Check out Palermo Hollywood and Parlermo SoHo neighbourhoods for great restaurants and bars that locals go to. Check out some great tango at the Club del Vino - not a touristy place.
