In Santa Susana, a hotel must offer a certain amount of upscale features to be designated 5 stars. These may include gourmet restaurants, on-site gyms, saunas and spas, complimentary luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their guest-centric service. You can look forward to things like nightly turn-down services, in-room massages and concierge services. Some may also offer special touches like welcome gifts.
