Concierge.com's insider take:
If you're very young and very hip, the 24/7 party theme at the unabashedly self-conscious Murano can be wildly fun. Opened in 2004 on the Marais's eastern edge, this "resort" is more like a playground for recording artists, movie stars, and fashion designers. In the 52 rooms, dimmer-controlled 1960s-style lighting splashes color over translucent organdy curtains, glass-topped tables, and flat-screen Bang & Olufsen TVs. Some suites have gas fireplaces or minipools, but you're not here to hole up in your room: The bar is a kaleidoscope of lights and flashing video screens, and it thumps with a superb sound system—even the restaurant has a DJ (book a table with your room). Not everything hits the mark, though: Night-vision goggles wouldn't be a bad idea in the dark halls and elevators; digital fingerprint scanners sound cool until they malfunction and you can't get into your room; and the much-touted spa still hasn't opened (there is, however, a fitness center). Not content with one hot property, Murano's owners opened the 40-room Kube Rooms & Bars in 2005, in a converted 18th-century townhouse on the edgy edge of Montmartre near the Gare du Nord. Like Murano, it's well-equipped: There's a computer in each of the 41 hyper-designed rooms, along with thermal blankets. Breaking a sweat in the fitness facility is one way to warm up before schmoozing in the Grey Goose Vodka Bar, where the down comforters, wool caps, and gloves aren't just for show—the temperature is regulated at a frosty 20 degrees Fahrenheit. Too cold and dazed? The steel-plated Lounge Bar offers more and different potables, as well as finger food conjured by chef Nicolas Guillard at any hour of the day or night. Here the modish, mostly beautiful guests chill out between modeling sessions and broadcasts (1–5 Passage Ruelle; 1-42-05-20-00; www.kubehotel.com).
