The apartment was much nicer than expected, and the surrounding area is very walkable. Some great chinese food just a couple of blocks away, and you can walk to and enjoy Old Port no problem.
Only issue was with check-in because the keys are located a half mile away from the apartment, and you need to use your phone to unlock the box to retrieve your key. Because we were coming in internationally, and only for a couple of days, we didn't purchase a data plan, and there was no wifi available at the mini-market. Thus, we incurred roaming charges just to get our key. Another tip: make sure you put in the MONTREAL address that Peter gives you for the key pick up (our Uber took us to the same address, but in a different city, which added 30 minutes and $45 to our Uber).
Other than the check-in process, I highly recommend staying at Peter's place. It was clean and spacious, the bed was comfortable, and the location is fantastic.
