Quite a nice hotel: A big open lobby with a well-stocked bar, a lounge with glass floor over a pond (you'll appreciate this after a couple of pisco sours, which are superb), and superb rooms.
One caveat: when we were in, the hotel was only 20% full, so it took 10 minutes for a 16th floor room to get hot water in the shower! Other than that, the "superior" room we received was just that---- a nice executive-quality room with separate shower and baths in marble, a corner view toward the parque metropolitaine, and a nice morning breakfast room. The concierge was truly helpful. The neighborhood was good, and the metro was a 7-8 minute walk away.
