Sam's place was the perfect spot for a 2 night dad-daughter trip. We had never been to Canada and this was a great first experience. Super convenient to walk to plenty of great restaurants and the cathedral, and just a few blocks from the metro. We went to a Habs game and by the time the game ended, we got the metro, and were walking through the door at Sam's home, it was just 20 minutes! And the free parking is 10 out of 10!
The only thing that could have been just a little better is that check-in time isn't until 4pm, and it costs quite a bit to check in early. 4pm seems late, especially if you have time-sensitive evening plans outside of the city, but maybe that's the nature of off-season traveling in MTL. Also, there is a social services building across the street that the local homeless tend to hang around. They were all pleasant and I never felt unsafe, but just something to be aware of!
Overall, I would absolutely stay at Sam's place again, and hope to do so in the summer!
