In Tum, a hotel needs to offer a specific amount of top-notch amenities to be designated 5 stars. These can include gourmet restaurants, saunas and spas, on-site gyms, premium bedding, luxury bathroom products and more. What also sets 5-star hotels apart is their guest-centric service. You can look forward to things like in-room massages, nightly turn-down services and concierge services. Some may also offer extra touches like a welcome gift.
