First let me start by saying Amy deserves her reputation as a superhost. She was very thoughtful and helpful from the minute I started asking questions about the unit 6 months in advance of my stay and throughout my time there. The most I ever waited to hear back from her was an hour or two, usually it was much quicker than that.
Amy's place is not on a main street but in more of an alley that has older buildings and newer ones so it's a mix but the location always felt safe. It is well located to some very cool streets within a minutes walk from the apartment with lots of restaurants and a 3 minute walk to Starbucks for coffee if you don't feel like making it yourself.
The only comment on the less than perfect side of things was noise. Because Amy has no control over this I can't say anything is under her control in this area. We were there for the Formula 1 weekend and lots of festivals were kicking off plus Spring had finally arrived. People walking by the unit after the bars closed could be heard on the inside but this was only an issue on the weekend. Weekdays it wasn't a problem and probably isn't a problem at all when the festival week ends. The only other noise item was a building under construction across the street where the workers showed up at 6;45 a.m. and construction started at 7 and went until 5 or 6 in the evening. Because we were gone all day it really wasn't a problem except for the early morning. Because I had foam earplugs for the race i slept with those and it helped a lot. Once the construction ends this wont be a problem any longer or when they get to a different phase where a small bulldozer isn't needed this will no longer be an issue at all.
Access to the Metro for the race and other areas is exceptionally convenient, the location of the unit is ideal for those that want to spend some time in Montreal. I would stay there again.
