If you decide to vacation at a 4-star hotel in Chantilly, you'll usually find loads of amenities to ensure you're relaxed, such as a gym, restaurant and pool. You can look forward to top-quality service and upmarket surroundings. Pick a 5-star hotel and you'll get a few extra bells and whistles — think on-site spas, around-the-clock concierge and nightly turndown services. You'll most likely get additional amenities and first-rate services at a 5-star retreat, though both are fabulous options for luxury guests.
