We stayed at Krista for competing reasons: business for me at first; family vacation later. It was perfect for both, conveniently located in the middle of fantastic restaurants and bars, relatively close to the Palermo parks and Botánico. Staff (especially Alejandro) were friendly and helpful finding restaurants appropriate for kids, making reservations, etc. Our room (we did have the suite) was gorgeous, and so was our kids' (separate bedroom with individual beds). Heating was a bit noisy, and the breakfast could be jazzed up a bit, but I'm really reaching here--we will probably stay here again if we go back to Buenos Aires.
