I didn't sleep here, but I attended an event here and intereacted with staff and priced out lodging.
The location SUCKS unless you're in Montreal for the mall and a view to two highways. (Or just stopping for a night's sleep bfore driving on one of those highways.)
Also, I didn't find the prices to be competitive either when pricing for my stay and we wound up sleeping somewhere nicer and in a better location and just came here for the event.
But the event staff is good and the staff is very friendly. The bathrooms are also exceptionally clean.
