Stayed here with two friends (three people total). Each of us had our own bed - two of which are in private rooms and one of them is in the corridor in between both bedrooms. Everything was clean, the bathroom is huge and you get tons of clean towels. Our fridge was stocked with water, soda, and a few beers. There's a coffee machine and a full kitchen.
Remi was very communicative, met up with us earlier than expected, and showed us around the place. He even came outside to grab a parking spot for us! There is a packet with some great recommendations for breakfast, restaurants, wine and liquor, etc. The bedrooms face the rear of the apartment so they are super quiet. The living room and dining area windows open up to the street, and it is a lovely view of Mont Royal Avenue. I will definitely stay here again when I am back in Montreal.
For those of you driving in, there is metered parking in front of the apartment. Remi and Marie have a map that shows you where the free spots are, and they translate the signs so you know how long you have to stay there. We got lucky because Remi found a spot for us on Friday afternoon and I left it there 'til we left on Monday morning. The building is located in a great neighborhood so we mostly walked. The few times we went to Old Montreal, we took an inexpensive Lyft or Uber.
Stay here. You won't be disappointed!
