We stayed at Green Hotel Confort during a trade fair at the Parc des Expositions, which is an easy 7-8 minute walk away from the hotel (as is the RER station), and the price for the Green Hotel was much cheaper than at other hotels in the area (including brands like Kyriad, Ibis etc who all jacked their prices through the roof for the trade fair). The hotel has a nice bar and restaurant area downstairs, but the trendy and contemporary downstairs décor wasn't carried on into the rooms that we stayed in upstairs, which were a bit on the tired side and could do with a big refresh.
