On Las Vegas Blvd occupying a tiny corner of City Center on the Belligio side. It was designed to be mostly condominiums, but they didn't sell well so you can get a room intended to be a condo. Outdoor terraces on some floors that you can actually sit on, and some wrap around the corner of the building. Rooms are very nice; some have small kitchens. Casino is small, because the lot is small. Lots of nice restaurants, mostly on the second level. View of the Belligio fountains from the Italian restaurant.
