The main difference between a 3- and 4-star hotel in Iona will be the standard of service and access to creature comforts. Three-star hotels are usually more budget-friendly and include the conveniences and services required to ensure your comfort, such as a gym, WiFi and breakfast. You can look forward to a bit more at a 4-star hotel — think upmarket interiors, deluxe toiletries and extras like on-site spa centers.
