The most obvious difference between a 3- and 4-star hotel in Congonhinhas will be the standard of service and availability of creature comforts. Three-star hotels are usually lower priced and include the services and amenities required for your comfort, such as WiFi, a gym and breakfast. You can count on a bit more at a 4-star hotel — think upscale furnishings, luxury bathroom products and perks like on-site spa centers.
