The Cassa Lepage was the greatest discovery of our recent three-week trip to Peru, Chile and Argentina. In some respects, it was unlike any hotel we have stayed in anywhere. Basically, it was the equivalent of having a studio in a chic, exclusive, art-focused building. The staff is delightful, the rooms (of which there appeared to be only about a dozen in total) are cut from former apartments in what was once an elegant hotel particulier, and the location is perfect for exploring some of central Buenos Aires livelier neighborhoods.
