In Newton, a hotel must offer a specific level of high-end conveniences to be rated 5 stars. These can include on-site gyms, spas and saunas, gourmet restaurants, luxury bathroom products, premium bedding and more. What also sets 5-star hotels apart is their outstanding service. You'll enjoy things like in-room massages, nightly turn-down services and concierge services. Some may also offer thoughtful touches like a welcome gift.
