The Myriad's guest rooms—serenely decorated in white with dashes of red and black—all have jaw-dropping views of the river and Parque das Nações, and cocoon swings from which to contemplate them. A panoply of amenities—from whirlpool baths or hydromassage showers to espresso machines—will make you feel thoroughly pampered. It took more than a decade to turn the 145-meter (476-foot) Vasco da Gama Tower, built for the 1998 Expo World Fair, into this hotel, but it was worth the wait. The 23rd-floor spa has a pool with whirlpool areas, flotation tank, sensations shower, sauna (with its own river view), steambath, and treatment rooms; there's also a 24-hour gym. Downstairs, the River Lounge restaurant ($$$) does brunch on weekends and serves classic Portuguese cuisine. There's piano music in the bar every evening, and a smoking lounge with a selection of cigars. Lisbon's hop-on, hop-off sightseeing buses make a stop right by the hotel.
