Take the "Black Line" (in French!!). No way to know: It was not on the email, it is not on the hotel website and I waited for the shuttle to the Mercure until I learned (25 minutes later when the shuttle came) that was not the right Mercure. What a waste of time. Friendly staff. That is all. To expensive for the service. Wifi sucks.
