In Bonga, a hotel must provide a certain level of high-end amenities to be designated 5 stars. These may include on-site gyms, spas and saunas, gourmet restaurants, luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their outstanding service. You can expect things like concierge services, nightly turn-down services and in-room massage. Some may even offer extra touches such as a welcome gift.
