I had a wonderful time during my short trip.
The house is old, so surely the facilities may not be as good as some newer places. However, it was still okay in general, and its age makes it a nice option for people who want to see what older houses are like (despite the age of the house in general, the washroom has been lately updated and was clean, as someone picky about washrooms, I'm generally satisfied).
The owners are very welcoming. I was a bit confused and nervous before my trip as I didn't receive instructions about check-in, but the whole process turned out to be easy and smooth. Simple vegetarian breakfast is included with no extra charge. The dairy products, the cereals, and the baked toast are great.
Generally good location with the Museum of Nature and plenty of good restaurants, pubs, and other food places around the property. It's not close to O Train but bus stops are within a few minutes' walk, and it's an easy drive from the airport.
Another thing I liked is that unlike some other B&Bs, I didn't find any stringent and hard house rule, instead things generally remained quite flexible.
It's worth noticing that the owners now have two (lovely) dogs, so for people who are not comfortable with dogs for any reason, better to notify the property beforehand so that you can make arrangements beforehand.
