These can include saunas and spas, on-site gyms, gourmet restaurants, premium bedding, complimentary luxury toiletries and more. What also sets 5-star hotels apart is their guest-focused standard of service. You can expect things like concierge services, nightly turn-down services and in-room massage. Some may even offer extra touches like a welcome gift.
