A very nice hotel, fantastic breakfast. It is reached by Metro line 1 (yellow), Important to exit at Esplanade de la Defense (second last station), get out in the direction of the train, spot a round building and walk around it anti clockwise until you find the hotel entrance. 100 m.
The hotel is situated at the end of a giant outdoor mall 2 km long and 100m across. With this advice you will avoid it.
Line 1 takes you to Paris center and most important places and connections, it is fast and frequent, thus the hotel is centrally placed in a practical sense. Although it doesnt seem so on the map
