When the in-laws come to town for a visit, send them straight to Fifteen Beacon, a hotel so classically elegant (and subtly opulent) they’ll never want to leave. The staff at this Beacon Hill hotel makes service an art form, so every customer feels like royalty. (The hotel even provides personalized business cards with guests’ fax and phone numbers to drop around town, as well as complimentary chauffeur service in a Mercedes-Benz sedan.) Rooms are decorated in rich earth tones with plenty of luxe accents (leather ottomans, working fireplaces) and are loaded with all the goodies you need, from Pevonia bath products to well-stocked minibars. Room service comes from the Federalist, the restaurant downstairs, which means you can leave not only the hospitality, but also the cooking, to the hotel’s accommodating staff.
