The big difference between a 3- and 4-star hotel in Barretos is the level of service and access to creature comforts. Three-star hotels are generally more wallet-friendly and include the services and amenities you need to ensure your comfort, such as breakfast, WiFi and a gym. You can expect a little more at a 4-star hotel — think upscale interiors, luxury toiletries and perks like day spas.
