In Warsaw, a hotel must offer a specific number of upscale features to be rated 5 stars. These may include gourmet restaurants, saunas and spas, on-site gyms, luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their guest-focused service. You can look forward to things like concierge services, nightly turn-down services and in-room massage. Some may even offer additional touches such as a welcome gift.
