The principal difference between a 3- and 4-star hotel in Oslund will be the standard of service and access to creature comforts. Three-star hotels are generally lower priced and offer the services and amenities required to be comfortable, such as a gym, breakfast and WiFi. You can count on a bit more at a 4-star hotel — think upscale furnishings, luxury toiletries and extra touches like spa and wellness centers.
