Hi Sheila, I thought someone else would have answered your question by now, but since they haven't, I will. I'm sure others will chime in. We usually stay at the Park Tower in Buenos Aires because it's a good location near Florida street and we usually have SPG points. The Park Hyatt and the Four Seasons are also really nice hotels in the Recoleta area. There's a good Hilton hotel in the Puerto Madera area where there's lots of restaurants and nightlife. You can also check Trip Advisor for lots of good information about hotels.
