the NH Maastricht is nice enough, with partcularely the lobby and restaurant areas looking good/fresh. If you have business at the convention centre or the hospital/university, the location is perfect with only a 100 meters walk necessary.
The food at the breakfast buffet and in the restaurant is OK, but nothing more. Based on the looks of the place i expected a little more interesting food.
The free WiFi is incredibly slow, and barely good enough for casual browsing. There is an upgrade available to buy, which cost 10€ pr. 24hrs. This increases the speed to around 1.5 mbits, a steep price for such a slow connection.
All in all an ok Hotel.
