Jim and Mable are very kind hosts. I was quite busy working for most of my stay here (and therefore maybe not the most social version of myself), but when I would be home late, Mable and I would hang out in the kitchen and chat, sometimes with one of my 'airbnb sisters', too :)
Jim gave me a Toronto Blue Jays hat, which was very sweet and allowed me to rep abroad. They took me out for dim sum one time and we cooked together a few times.
I found the room and house very clean, and the bed very comfortable. The bathroom is nice and comfortable, too, and the laundry facilities are very clean as well. When my mom came to visit me, Mable was very flexible about that, which was absolutely great!
The kitchen is well-equipped. I didn't cook too much, because I tried to time it when nobody was there, since cooking is a bit stressful for me when there's too many people around, and while I was there, it could be rather busy. At other times the house was pretty much empty, though, so then I could cook and relax :)
House rules made sense and were easy to follow. I was very happy with the disciplined dishwasher-loading policy :)
The only thing I would recommend is to make sure that your daily rhythm matches that of the house. The room being right under the dining room and kitchen does make it quite hard to sleep while others are (getting) up, even with earplugs (at least for me). Also: the room is a bit dark. I like waking up with daylight, which is a bit precious in the basements, but that's to be expected, of course.
All in all I can see myself staying here again during my next visit (which I hope will be soonish).
