We enjoyed our ten-day stay at Yang’s. The place was clean enough, the bed was comfortable, the apartment came with plenty of supplies (paper towels, bathroom tissue, laundry detergent, dishwashing liquid …), and the soundproofing was excellent (we never heard city noises from outside, or noises from the neighbours). The location is great: you are within walking distance of pretty much everything: tourist attractions (downtown, Chinatown, Old Montreal, Mount Royal …) as well as conveniences (grocery stores, restaurants, shops …).
The only thing one should keep in mind is the size of the apartment. We expected it to be small, but it was actually smaller than we had anticipated: when the Murphy bed is down, there is about 100 square feet of living space. It did not really bother us because we were out most of the time and we are not large people. However, some folks might find it somewhat challenging.
Other than that, everything is hunky-dory and we recommend Yang’s place.
