I stayed for five months in this apartment. It's a very convenient location, close to the Plateau, downtown, Chinatown and Old Port, and it's on the orange metro line which can you just about anywhere. Although it did not always feel the safest (large police presence, arrests, drug use on the streets).
The apartment itself is nice, spacious, well-equipped; however, it wasn't the cleanest when I got there - some kitchen items had been put away dirty, there were moldy coffee grounds in the coffee maker, dust bunnies in corners/under the bed, and some stains on the curtains/walls. The bed is comfortable, the couch and kitchen chairs are fine. The screens on the windows are not well secured and come loose. The back balcony is nice and having a fully private entry is great. The lock on the door is extremely difficult to open when it's cold out (it took two hands to turn the lock in January).
It's also a surprisingly noisy spot. It's a dead end road, so I thought it would be quiet, but the snow from the surrounding streets is all plowed to the end of it. Big trucks come in the middle of the night to take the snow away, which regularly woke me up. (In the warmer months, this is not an issue.)
Karen is a kind and responsive host, but not all the problems were fixed rapidly (or at all). The sheets had holes in them when I arrived and it took several days to get new ones, and it was months before burnt out lightbulbs were replaced.
Overall, I would say it's a little overpriced for what it is, but a very convenient location and a spacious place.
