We were a group of three and found Phil's apartment to be very spacious, comfortable, and clean. The decor is lovely and the location is perfect for exploring old Montreal. Phil was very communicative and was always available if we had any questions.
The only thing to note is that the apartment is above a few restaurants/bars, so there is a little noise at night, and it seems like those places may dump out their recycling in the wee hours just below two of the bedroom windows! It didn't bother us, but if you have young kids who are light sleepers, it might be worth putting them in the bedroom that faces out on the river.
We definitely plan on coming back and staying at Phil's beautiful apartment!
