Nice place, great location and close to all attractions for a first timer to Montreal. Parking is a challenge but that will be the case for any building on this location. Unit has every home essentials necessary!
One disappointing thing with chains like Sonder inside Airbnb is that you lose personalized experiences that AirBnb is meant for. With Sonder, you have to go through a computerized customer service system; bot chat responses are from templates; cannot casually chat for local attractions; extremely unresponsive with requests even if they say 1 hr response time on the app (my experience was when I asked for just a 1 hour late checkout. I am okay even if they decline the request but if they are unresponsive it is hard for my planning).
