Ambassador Hotel 
Frommer's
Fodor's
Frommer's "The narrow indoor pool is a plus, as is the view from the roof restaurant"
Fodor's "Czech crystal chandeliers and marble floors in the reception area offset the otherwise businesslike surroundings, while an excellent top-floor restaurant, two bars, and a pool and fitness center are among the many amenities"
