My wife and I booked this stay months in advance, received immediate confirmation and paid on the spot. Fast forward to check in day, we’re driving into Montreal and hadn’t received check in instructions yet, so message the host asking for the instructions only to receive a cancellation response and be told the system showed we hadn’t paid so he rented to someone else. Again, we paid when we made the booking and if there was any question on the owner’s end, why he never reached out to me I have no clue. My theory is that he later realized he could charge a much higher rate than we paid because it was the weekend of the Formula 1 Grand Prix. Since it was the weekend of the Grand Prix , there were very little accommodations available and the prices were absolutely ridiculous. We wound up having to stay in 3 place in 4 nights and pay quadruple the amount.
