I stayed for 2 days at a conference. It is about 400 meters from the metro. In this period there are works for a new line and therefore some discomfort. Good quality hotel and well appointed rooms and bathrooms. Friendly staff and really helpful concierge service who immediately found me the room even if I arrived early. Breakfast not very varied but waiters ready to provide what was missing
