I booked a room at the Sand and Stone hotel when I was looking for low-cost accommodations for a short stay on short notice in downtown Montreal. It served that purpose well, though there are a few things visitors considering a stay here might want to know before making their choice.
Pros: The room was as advertised, and the price was quite affordable for a stay downtown in a major city. The room was clean, and I appreciated having a sink within the room given the shared bathroom situation. The location was conveniently close to a metro station and to tourist attractions and restaurants.
Cons: Lots of city noise, so be sure to bring earplugs. Some visitors may not feel comfortable walking around the area alone at night, though I wouldn’t personally describe it as “unsafe.” There are no deadbolts on the room doors, and no safes/lockboxes provided. The elevator does not go to the sixth floor, so if you need elevator access be sure to ask for a room on a lower floor.
