The key difference between a 3- and 4-star hotel in Sierras Bayas will be the standard of service and access to creature comforts. Three-star hotels are usually more wallet-friendly and include the services and amenities you need to ensure your comfort, such as breakfast, a gym and WiFi. You can look forward to a little bit more at a 4-star hotel — think upmarket furnishings, deluxe toiletries and extras like on-site spa centers.
