I finally got this after starting at $90 and increasing incrementally by $2 and using 3 Montreal areas (financial, festival, and Old Montreal) It took a few days, looks like a decent property in a central location downtown.
Room Cost (avg. per room, per night): $107.00 (USD) Number of Rooms: 2 Number of Guests Per Room: 2 Number of Nights: 2 Room Subtotal: 428.00 (USD) Taxes and Fees: $57.56 (USD) Total Room Cost: $485.56(USD) Booked this on Sept 1 2012. From Aug 28-31 I had failed bids in this area and "City Center" from 90 to 106 USD for 5 stars. As well failed bids from 78 to 89 USD in the 4 star category in the same areas of "City Center" and "Central Canals"
