We always enjoy staying here. Have been doing so since 1980 while going or coming through Montreal. Reasonable rates and clean. The 3rd floor is newer but all the rooms are clean.
Even though the shuttle is scheduled every half hour, it can fluctuate so be ready. We always give ourselves plenty of time at the airport so catching a 5:30 or 6:00 AM is good but we try 5:30.
Staff was friendly and we do enjoy our stays here.

Standard Best Western rooms. Staff were quite expressionless and not helpful. Bathroom was a little outdated. If you intend to make use of shuttle, call ahead to front desk. We were intending on using shuttle at 6am, got there at 5:55 and it was gone. Had to wait anoter half hour. If you can afford a few more bucks, go with the Marriott.

Stay there most of the time near my meetings, Airport and shops.
Clean, reasonable price and most rooms are spacious with new TV's.
Staff and service generally good.
Food and room service below expectations. Wifi quality good but parking can sometimes be an issue.
Good value for the price.

Nice and close to Dorval, only about 3 minute drive. Free shuttle service every 30 minutes. Friendly front desk staff, and the rooms, although standard hotel type, were comfortable and with nice bedding.
We used our Aairmiles, and would stay there again.
