The big difference between a 3- and 4-star hotel in Nova Gradiska will be the quality of service and availability of creature comforts. Three-star hotels are usually more pocket-friendly and provide the services and conveniences required to be comfy, such as a gym, WiFi and breakfast. You can count on a little more at a 4-star hotel — think upscale interiors, premium toiletries and perks like on-site spas.
