We stayed 3 weeks in Bui's apartment, and overall it was a good experience. His family lives upstairs, and they are super friendly. We got to play with our daughter in their garden, and they kept giving us home grown cherry tomatoes and they were delicious !!! The neighborhood is a safe and quiet area, really good for families and you have a huge park just 500m away. It is also quite easy to get around with public transport, even if you have to walk a bit.
The apartment has everything you need, the bed was really comfy. It is a basement apartment, but you have bigger windows in the livingroom which makes it not bright enough.
Overall would recomend for longer stays in Montreal :)
