If you choose to vacation at a 4-star hotel in Saint-Gervais, you'll usually find loads of amenities to keep you comfortable, such as a gym, pool and restaurant. You can look forward to high-quality service and upmarket surroundings. Choose a 5-star hotel and you'll have access to a few more perks — think around-the-clock concierge, on-site spas and opulent turndown services. You're likely to get extra amenities and first-rate services at a 5-star stay, but both are fabulous options for luxury guests.
