· Free water is one of the first items listed, and while it's true that you can always just stick a glass under the faucet and drink up, Starwood offers an assortment of free water bottles (Fiji, Nestle, Smart Water) to its SPG members. Meanwhile, hydration snobs should also check out the Shore Hotel in Santa Monica, CA, which has a nifty water bottle fountain; and the Club Lounge at Grand Hyatt New York has a special purified water dispenser with not one, not two, but three spigots.
And let's not forget about the fancy pants "Ritz water" we've been spotting recently.
· As far as hand-written notes from housekeepers? Eh, that's a tough one. Though we certainly enjoyed the personalized stationary that was waiting for us when we checked into the Mandarin Oriental San Francisco last year. We also loved this story of Kimpton welcoming a guest with free candy and a humorous hand-written note gently denying the guest's request for a bathtub full of candy.
· Happen to be in need of an air purifier? Well, you'd best book a stay at Boston's XV Beacon, where all rooms are hypo-allergenic and come fitted out with ViraTech UV-400 advanced air purification systems. Meanwhile, Hyatt is a good, reliable brand when it comes to clean-air rooms, as they launched their airborne-bacteria-eliminating Respire Rooms back in 2010.
· And finally....free internet? Well, you'd probably do best just taking a browse through our most recent annual WiFi report. We trust you'll find everything you're looking for right in there.
