The station is convenient, you can get acquainted with the information in time, eat, relax, go shopping. There is both the metro and the RER. We left here for Normandy.
Very convenient! It's easy to navigate. You can have a snack in the cafe. Buy a meal with you on the road in Monopri. Go shopping. There are a lot of police officers. There are always employees who can be asked about tickets, where and how to buy them.
It is difficult for a foreigner to figure it out, but there are those who help to buy a ticket and advise on all issues for free. It is relatively clean, but there are delays in trains and because of this there are not always enough tickets for everyone.
