The big difference between a 3- and 4-star hotel in Mascot will be the quality of service and availability of creature comforts. Three-star hotels are usually more wallet-friendly and provide the services and amenities required to be comfortable, such as breakfast, WiFi and a gym. You can expect a little more at a 4-star hotel — think upmarket furnishings, luxury toiletries and extra touches like on-site spas.
