The main difference between a 3- and 4-star hotel in Flat is the level of service and availability of creature comforts. Three-star hotels are generally more budget-friendly and include the conveniences and services you need to be comfortable, such as breakfast, a gym and WiFi. You can look forward to a little bit more at a 4-star hotel — think upscale interiors, luxury toiletries and perks like spa and wellness centers.
