The latest entry in our travel address book is Unlisted London, a new on-call service that dispatches stylists, masseurs, facialists, and manicurists to your hotel room. After a long flight to Heathrow, we put the company to the test with a request for a hairstylist. In two hours Simon McAndrew (one of the city's hair gurus, a fashion week regular) arrived, blow-dryer in hand. Not even the hotel spa can work that fast. Rates, from $65; 44-870/225-5007; www.unlistedlondon.com.
