I stayed at the Courtyard Marriott in Colombes during a business trip to Paris. Since it was walking distance from the office, it was very convenient from a working point of view.
But I think it is a nice hotel from a tourist's point of view as well, because there is a train station very close to it. That train takes you to the city centre in approx. 20 minutes. The famous La Defense with its Grand Arche is even closer and can be reached by bus in 10 minutes.
The breakfast buffet was quite ok, although I would have liked to see a little bit more variety.
