In Gaastra, a hotel must offer a certain number of upscale conveniences to be designated 5 stars. These can include gourmet restaurants, on-site gyms, saunas and spas, luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their extraordinary service. You can expect things like in-room massages, nightly turn-down services and concierge services. Some may also offer extra touches like a welcome gift.
