The de la Cruz collection belongs to one of the grandes (and most gracious) dames of the art scene, Rosa de la Cruz, who frequently opens her art-filled house to the public (by appointment). Every nook of her Key Biscayne home — from the living room to the laundry room — is filled with works by the likes of the video artist Aida Ruilova and the painter Martin Kippenberger as well as a psychedelic installation by Assume Vivid Astro Focus.

Via Modern Art Obsession, found in the Wall Street Journal:

The four-year-old Art Basel Miami Beach fair attracts thousands of visitors to its contemporary art sales and industry parties, but increasingly some of its biggest draws are tours of art owned by wealthy collectors, which offer a glimpse of some of the city's most lavish homes and properties. Most of these are invitation-only, but it's sometimes possible to get in through a local gallery or the fair office.

...

While it is all part of the fair's goal of sharing art, these open houses can offer a financial benefit for collectors, who sometimes get discounts from dealers in exchange for prominently displaying works in their homes. Zach Feuer, a New York dealer, says that last year he lowered prices for three Miami collectors who showed the pieces in their home tours.
