A very large organized train station, a place for taxis, very beautiful also, a work of art! There are many different establishments, restaurants, hotels nearby - for every taste and pocket!
Paris railway station, where commuter trains leave. We were leaving here on a high-speed train to Monaco. The old beautiful station building. Cool platform overlaps. Well, the rest is just like at any train station - people, noise, dirt.
A very beautiful historical building. Convenient location, the metro is very close. There are cafes, luggage storage and everything you usually need at the train station. There is a small kiosk near the platforms with TGV trains where I bought one of the most delicious croissants in my life.
