This apartment is centrally located and within walking distance of the old town and UQAM. It's perfect for exploring most parts of the city (including a few blocks from Chinatown). It is one of the more clean Airbnbs I've been in. All of the modern appliances are fairly new and convenient. The owner does a good job of maintaining.
For the drawbacks, it is located across the street from a hospital so expect hearing ambulances round the clock. Additionally, the Berri metro stop is nearby so there's occasional roaming junkies and beggars. The worst part for our experience is the wifi connection. Owner represented that the speed was 60 mbps before our booking. However, when we arrived, we experienced 4 mbps and even worse. There is no router or extender within the apartment and it's difficult to complete work online. The owner claimed to rectify by offering an extender, but this was never completed and our entire stay had very poor wifi.
