The biggest difference between a 3- and 4-star hotel in Piedmont will be the quality of service and access to creature comforts. Three-star hotels are usually more economical and provide the services and amenities you need for your comfort, such as WiFi, a gym and breakfast. You can look forward to a little bit more at a 4-star hotel — think upmarket furnishings, deluxe toiletries and perks like on-site day spas.
