Sam's place is a great value if you're looking to stay in Old Montreal. We enjoyed our stay and were walking distance from many tourist locations. Loft was clean, easy to find, and has multiple parking lots nearby if you arrive by car.
The only issue we had was a late check-in due to unpreparedness by the cleaning staff. Sheets and other essentials were not yet washed, which caused us to be delayed in not only arriving to the apartment but in getting settled in. However, Sam's assistant Totty was prompt in replying to my messages and helped us with clean bedding.
Overall, our experience in the loft was a very positive one. The hiccups we experienced were purely because of lack of communication; the loft itself is a great stay and one that I would recommend.
