In Zwiesel, a hotel must provide a specific number of upscale features to be designated 5 stars. These can include saunas and spas, on-site gyms, gourmet restaurants, 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 in-room massages, nightly turn-down services and concierge services. Some may even offer special touches like a welcome gift.
