In Jena, a hotel must provide a specific level of top-notch amenities to earn 5 stars. These can include on-site gyms, spas and saunas, gourmet restaurants, premium bedding, complimentary luxury toiletries and more. What also sets 5-star hotels apart is their superior standard of service. You can look forward to things like in-room massages, nightly turn-down services and concierge services. Some may even offer extra touches such as welcome gifts.
