I stayed 10 nights and worked remotely for 4 days during my stay here. It's a great environment for remote workers -- clean & comfortable, fast internet, quiet & respectful guests and neighbors.
The location is going to be hard to beat as well -- within two minutes of walking there are great parks & trails, grocery stores & shops, plenty of bars & restaurants, and easy access to public transportation.
Simon is a great host -- super friendly, very knowledgable, and he keeps the Airbnb in great condition. I will stay here again the next time I'm in MTL.
