What is your definition of "best"? Motel LaSiesta on Taschereau offers a good quality/price ratio. Four hours for 38-50$, depending on the type of room. Small but reasonably clean and jacuzzi in the room for the 50$ rooms. Pay cash, no questions; they just take note of your licence plate.
For a more sophisticated lady, the Motel Royal Labarre offers some theme rooms: http://www.motelroyallabarre.com/
There is also Econo Lodge on Taschereau in Brossard - former incall location of "Emotions" - $33 for 3 hours, 4 hours also available. Pay cash, ask only for license plate number.
