The hotel has been renovated recently, and the rooms are quite big, even including a well-equipped kitchen. Before being a Marriott, it was a Conrad hotel and it seems they have kept many features. It is also very well located!
The breakfast is excellent, and it changes everyday.
The only aspects I would mention are the cleaning service that 'forgot' to clean our room twice, even the green light was on out of the room (it is a very domotic room in all senses). And the air-conditioning seemed to be switching on when it considered, not when we switched it on intentionally.
