Not sure was a art nouveau renovation is but I like it. The architecture is what grabbed my attention and maybe that is art nouveau? Either way the all white architecture mixed with modern design is stunning. The floors are quite amazing and intricate, they are found throughout the entire house. The design is well thought out, so clean and minimal. This was an American couple that wanted a second house and chose this place to do a complete renovation on, with Vilablanch at the helm. Together they did a fantastic job.
