I believe they are more of an European hotel chain. We have stayed at
www.ibis.com while we were in London, Paris, Madrid, and Barcelona.
If you're looking for a cheaper, yet comfortable place to stay, then I highly recommend their Budget hotels. I believe they have the Budget, the regular and the Business hotels. Correct me if I'm wrong.
However, the Paris Ibis was our favorite, as they provided free croissants at the reception, every single day!
