We really liked the M Montreal. It was centrally located (though a bit dodgy at night) and the place was clean, the staff were friendly and very helpful, and the room very large with good amenities, especially given the price. Our first night, someone was hosting a very loud, very late party, but when we spoke with the staff the next day, they let us know that if it happened again, to let them know and they would shut it down. The roof deck is fantastic though the hot tubs were always busy and, given COVID, we weren't comfortable getting into a tub with a lot of folks. It would have been nice to be able to book time for this. We would have no hesitation about staying here again.
