Star Service
Oyster "The hotel is surrounded by a choice of restaurants, but
also has one on-site as well as a lounge bar and a small, simple fitness center with modern equipment"
Star Service "The gym on the fifth floor is a perk with its aerobic stations and multistation weight machine, but it closes at 10 pm"
