Very good

"Totally worth it. When you purchase the service you could choose which hour you wish to enter the museum. Bear in mind that the earliest hour was 13:00. However even if you enter at 1 PM you will have enough time to explore. One thing that could be improved: When ... you take the tickets from the office of Pariscityvision they should give you a little bit more info from where to enter, because it is difficult to find it."
