Hilton Buenos Aires
Great, spacious lounge. Pool table, sofa, big screen TV, free snacks/soda, and free wine at happy hour on weekdays (5-7 pm if I recall correctly). Food was consistently average to above average (mostly small finger foods). The lounge itself overlooked the pool which was 1 floor down. You could walk through and go down to the pool with your key card. There was also an enclosed sun room where you could sit and read while looking out at the pool area.
