I very much enjoyed my stay at La Saint Paixe in Montcalm. Check-in and check-out were seamless and done through codes you're provided by email, and the room was both comfortable and super quiet. While I didn't use it, there's a nice outdoor terrace on the ground floor with tables and chairs. The free parking both in front and behind the building were also a big plus!
While the area immediately surrounding the building is pretty quiet (good for sleep!), the building is a stone's throw from Cartier, right up the stairs from Saint Roch, and a 10 minute walk or so from the core part of Saint-Jean Baptiste. And, in the nicer weather, you have an Avelo bikeshare station approx. a 5 minute walk from the hotel to get around elsewhere!
