The key difference between a 3- and 4-star hotel in Llupia will be the quality of service and availability of creature comforts. Three-star hotels are typically more affordable and include the conveniences and services you need to be comfortable, such as a gym, WiFi and breakfast. You can look forward to a bit more at a 4-star hotel — think upscale décor, luxury bathroom products and perks like on-site day spas.
