Overall it was a really nice stay! Our group of 11 had a nice time. Tania was quick with communication and allowed us to check in early. You get a digital manual when you arrive which explains check in, parking, restaurants near by etc which was a really nice touch for those who have never been to Montreal before.
The outside of the unit isn't the nicest, and when walking up the stairs there was a musty smell, but not a big deal. Once you enter the unit it is really nice! Very big, a lot of space and very clean. It is also in a good location near a lot of restaurants, attractions and bars. Metro is very accessible too, about a 10 min walk to Berri Uqam.
One thing to note is one of the rooms doesn't have a door, her ad mentions this but I skimmed through it quick and didn't notice when looking at the pictures which was a surprise when arriving, so just take note of that if looking for some privacy.
Thanks for the great stay!
