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