I did not meet Samuel in person, but he was a great host. He was very quick in his responses to questions and requests. The apartment is exactly like pictured. The whole place is quite cozy and welcoming. The location is only 3 blocks away from the metro and there are a lot of good restaurants in the area as well as being close to major universities in Montreal. For grocery shopping it is about a 10 min walk but there is also a bus right in front of the building that takes you to further markets and a walmart. There are also two convenience stores just outside the building which is great for last minute buys. The heating is also very good and you never feel cold there. Overall, I would definitely recommend booking here.

Something unique that what happened to me while in this apt was that one of the styrofoam boards in the ceiling on top of the bathtub fell into my tub from being soaking wet from a leaking shower in the upstairs unit. But when I sent Samuel an emergency message, his employee came over to throw away all the debris and they fixed the leaking and the ceiling in 3 days.
Here are other little problems that you may encounter during your stay:
The kitchen is a bit small and there is no counter space to cut your food, so you have to improvise. The stove is also old so it takes a little to get used to them.
Sometimes the people living in the other units would violate protocol and smoke inside the building. Sometimes you get whiffs of cigarettes and sometimes worse things.
The walls are a little thin and sometimes you can hear the neighbors but not always. Most of the time the apt is quiet.
The building itself is old so the air sometimes feels stuffy and the elevators are of course, a bit run down and sometimes they break or they take long to get to you since only one of them is working.
The laundry room in the basement has a lot of washers and dryers which is good, but the floors and overall aesthetics of the basement is very different from the other floors so it almost looks like a different building going down there.
Though there are issues like mentioned above, they are mostly nuisances that can easily be tolerated. I definitely recommend this apt for you for long stay.
