In Blackstock, a hotel needs to provide a specific number of high-end amenities to be designated 5 stars. These can include on-site gyms, spas and saunas, gourmet restaurants, premium bedding, luxury bathroom products and more. What also sets 5-star hotels apart is their exceptional service. You'll enjoy things like concierge services, in-room massages and nightly turn-down services. Some may even offer extra touches like a welcome gift.
