The most obvious difference between a 3- and 4-star hotel in Sint-Gillis will be the quality of service and availability of creature comforts. Three-star hotels are generally more wallet-friendly and offer the services and conveniences you need to be comfy, such as a gym, breakfast and WiFi. You can expect a bit more at a 4-star hotel — think upscale furnishings, deluxe bathroom products and perks like spa centres.
