These can include gourmet restaurants, on-site gyms, saunas and spas, premium bedding, luxury toiletries and more. What also sets 5-star hotels apart is their guest-focused service. You can look forward to things like concierge services, in-room massages and nightly turn-down services. Some may even offer special touches like welcome gifts.
