Have stayed twice this year at the Mercure and find it very good value for money. Rooms are good and I quite like the location. We had a convention at big sight which meant a few train changes so no big deal. Mini bar is free (excluding beer) but there are a few convenience outlets across the road anyway. Plenty of local eateries around including an excellent schnitzel place, and a burger/fish&chip shop in the direction of the airport. K K line rail is OK or you can go back a couple of stations and transfer to the monorail.
