Oyster "A pleasant indoor garden and fitness center are nice amenities, but there is a fee for covered parking and the location isn't walking distance to Milan's popular attractions"
Jetsetter "There's also an on-site fitness center"
Lonely Planet "The bars and restaurant are all worth a visit (check out the Garden Bar with it's huge ceilings), and there's a decent gym and great business facilities"
Frommer's "A zen-inspired spa has opened on the seventh floor and there’s a small gym to work off the excesses of Milan's pasta and pizza restaurants"
