For a trip to Disney Paris, you can't really do much better than this place. It's right next door to the Val D'Europe station which is 1 stop (5 mins) from the main Disneyland stop. Also, it's really easy to get back as all trains from that stop go through Val D'Europe so you can't go wrong. The only thing I would advise is to download the IDF Mobilites App and buy train tickets in advance. ANOTHER POINTER: The Val D'Europe train station is separated into two parts, either side of a main road. We often got on the train at the southern station which seemed quieter and exited on the northern part of the station which seemed closer to the commercial area and much busier. It was confusing at first, but once you understand that the station has separate entrances it's easy enough to work out where you are.
The staff at the hotel are all super helpful, speaking fluent English. The breakfast is fairly basic, but better than expected from other reviews. You still have certain hot foods like bacon, eggs, sausages & different toasts (sourdough etc). Along with usual continental stuff like croissants and other pastries.
The rooms are very comfortable and the hotel has a stylish, modern feel. We often came back late and the bar serves casual snacks like sandwiches, chips, paninis, nachos etc for a quick bite.
We didn't explore the area much. The Val D'Europe area looks quite commercialised, but if you want a fuss-free meal there are reasonable restaurants around the main train station.
