The main difference between a 3- and 4-star hotel in Balcarce will be the level of service and access to creature comforts. Three-star hotels are typically more affordable and provide the conveniences and services you need for your comfort, such as WiFi, a gym and breakfast. You can expect a little more at a 4-star hotel — think upscale interiors, deluxe toiletries and extras like on-site day spas.
