WOW, the location of this place was phenomenal! 30 second walk to the Basilica, and all the amenities you would need are very close by.
Be sure to check out Paquebot Cafe just around the corner, best cafe and the guys there are awesome.
90% of the main attractions were within walking distance, we did take the metro a few times just to save a bit of time when going as far as St. Joseph's Oratory, but it was super easy to navigate.
Julien's space was very nice, though this was the first time I've stayed at an AirBnB where someone normally lives there and it isn't just a rental property (ie. all his belongings were there) so that was a bit different for me.
