In Paris, a hotel needs to provide a specific amount of upscale conveniences to be rated 5 stars. These may include gourmet restaurants, saunas and spas, on-site gyms, premium bedding, luxury toiletries and more. What also sets 5-star hotels apart is their guest-focused standard of service. You can expect things like nightly turn-down services, in-room massages and concierge services. Some may also offer thoughtful touches such as a welcome gift.
