Michelin Guide
Oyster
Star Service
Michelin Guide "It offers contemporary
design in the technically well-equipped rooms, in the 'Ice Bar' for
smokers, and in the 'Fit & Well Health Club'"
Oyster "The hotel has a show-stopping bar made from a refrigerated block of ice, a restaurant serving international cuisine, a host of business amenities, and a large gym"
Star Service "Many of these latter units sport Murphy beds that fold into walls for entertaining, but a private lounge is lacking"
