Clean, very well equipped gym. Has a dark (low light) theme which sets a mood for "night club" effect/ambiance. Plenty of workout space, areas for stretching, floor work & private training. Additional rooms for cycling, golf and other specialties. This is within the Hilton Boston Park Plaza Hotel, as a hotel guest, I use my own room to shower, but I'm sure the gym has great facitilities.
The team at the front desk are always welcoming, the club is tidy and clean, and members are generally extremely courteous and polite in sharing equipment. A great experience!
