First of all, the apartment itself was very beautiful, and suited our needs well. I especially loved the real wood-burning fireplace and the huge corner tub! All the reviewers talking about the loveliness of the space and the courtesy of the hosts are absolutely right - it was great.
The neighborhood, though, left something to be desired. Hochelaga-Maisonneuve is definitely up-and-coming, but not quite there yet. Rue Ontario, a lively shopping district, is a ten-minute walk away. But the (major) street the apartment is on is stiil recovering after a history of sketchy activity. It's not the hosts' fault, but we did see people engaged in sex work in the alley behind the building the first night we were there, and the street in front had people hollering at all hours. Though we were undoubtedly safe, it made the surroundings feel less safe to us.
Overall, though, if you don't mind a slightly scrappy neighborhood and a bit of a schlep to downtown, it's a great place at a good price!
