El Cassco Art Hotel
This will make me sound way cooler than I am, but when I was in Bariloche, Argentina (you know, up in the Lake District on the shores of Lake Nahuel Huapi), I stayed in this 31-room luxury boutique hotel owned by a successful gallery owner from Buenos Aires., Each room features original works by 31 artists so guests can enjoy their own mini-gallery with an incredible lake view. All-in-all, there are over 500 pieces of original art and sculpture scattered in and around the property, including their award-winning restaurant.
It was a great trip (not to mention riding horses across the Pampas with the Andes Mountains as a backdrop), and I came away with both a greater appreciation for modern art, and a desire to go back.
Great for a board retreat or small incentive, check it out at http://www.hotelelcasco.com/en/
