In Artois, a hotel must offer a certain number of upscale features to be rated 5 stars. These can include saunas and spas, on-site gyms, gourmet restaurants, luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their extraordinary service. You can look forward to things like nightly turn-down services, in-room massages and concierge services. Some may also offer thoughtful touches such as welcome gifts.
