In Casa Blanca, a hotel needs to offer a specific number of upscale conveniences to earn a 5-star rating. These can include on-site gyms, gourmet restaurants, saunas and spas, complimentary luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their superior service. You'll enjoy things like in-room massages, concierge services and nightly turn-down services. Some may also offer special touches like a welcome gift.
