The big difference between a 3- and 4-star hotel in Nambuangongo is the quality of service and access to creature comforts. Three-star hotels are usually more economical and offer the services and conveniences you need to be comfy, such as a gym, breakfast and WiFi. You can look forward to a little bit more at a 4-star hotel — think upscale décor, luxury toiletries and perks like on-site spas.
