If the thought of sleeping in a fish market doesn't sound appealing, think again. All right, this is not a working fish market, but traders once haggled over catches of hake and bass in this iconic 1930's building. Its cool Art Deco lines make it a lovely alternative to older-styled hotels downtown. The high-ceilinged, glass fronted lobby, in particular, is a light-filled architectural jewel. Sip a martini or porto-tónico in the bar and you can imagine yourself on a Jazz Age cruise liner. The 33 Alameda restaurant is another Deco beaut featuring onyx columns and vertical lighting, not to mention an excellent modern take on Portuguese and Mediterranean cooking. As for the digs: bedrooms and bathrooms are large and handsomely color coordinated. Some offer river views. The historic tram line stops just outside to whisk guests downtown.
