Communication was great - rest assured they are professional and responsive and did not cancel on me last minute (as I have experienced with others).
The space looks like the pictures. Key pad entry was clutch. Parking is relatively easy in the neighborhood. You can get a resident sticker and have $6 daily parking if you choose by going to the corner market, but it wasn't open early mornings and we just ended parking at meters or free space. Not an issue. Beds were super comfy - foam mattresses. Plenty of space.
Tip: remember to bring your own toiletry.
Plateau is a wonderful, lively local hip without pretentiousness. There are stores and cafes and restaurants packed on every block and a wonderful park down the way. Bixi bikes are the way to go as there's a lot of prospected bike lanes and a station a block away. If you've been to Montreal before, this is a great next step place to be away from tourists and downtown and experience another flavor.
