I've seen some less than great reviews and comments and I had some trepidation about this booking. Thankfully I can say we did not experience the majority of some of the issues people raised.
Pros: this is easily one of the nicest airbnb's we've stayed at. The apartment is very clean and very well maintained and the pictures are very accurate. Check-in was super easy and we had zero issues getting the key. Communication with Doris was seamless and she responded within 10-15 min, so full marks there. Cons: it is indeed a bit noisy on the street and we were woken up several times both nights we stayed here. We're both originally from Montreal and we know this area well, so caveat emptor. The trade-off is while it's a bustling and busy street, it has a lot of great bars and restaurants. Montreal Plaza restaurant is a 2 min walk and on the block; it's generally considered one of the best restos in Montreal.
