Fodor's Expert Review Millennium Gloucester

Located next to a conference center and opposite a Tube station, this is very much a business hotel. The lobby is sleek and minimalist with polished marble floors and soaring blonde-wood columns, while the guest rooms are similarly tasteful (though bordering on bland) with neutral creams and earth tones complemented by light-wood desks and leather chairs. There are two bars and several restaurants (plus an attached casino), which means that you don't have to go out if you'd prefer to stay in.
