In New Haven, a hotel must offer a specific level of high-end amenities to earn a 5-star rating. These may include gourmet restaurants, saunas and spas, on-site gyms, premium bedding, luxury toiletries and more. What also sets 5-star hotels apart is their guest-focused service. You can expect things like in-room massages, nightly turn-down services and concierge services. Some may even offer additional touches such as welcome gifts.
