My boyfriend and I had a lovely 3-night stay at Benjamin's place. The location is perfect - right in the heart of the Plateau neighborhood. We could walk to both the old port or Mile End in about 20 minutes, and was very easy access to other sites as well. We felt safe enoug. The apartment is overlooking the alley side of the building so although it's on a busy street, it was fairly quiet at night. The including parking was extremely helpful as well, my Impreza fit just fine but might be difficult if you had larger car. We used the Bixi bike system to get around (getting a monthly membership for $18 canadian/$15 US saved us a lot!) and there is a dock directly across the street.
The apartment itself is new, clean, and quite comfortable. Kitchen is not super well stocked but there is enough equipment to cook a simple meal. Our only real complaint was that the bedsheets were very pilled which was uncomfortable/scratchy to sleep in, but I mentioned it to the host and hopefully he will be replacing them.
Overall a great find!
