Make sure you mention a/c to the host if you want it before your arrival. She works as a guide in Quebec province so she isn't always able to respond quickly due to lack of cell service and her job needing her 110% focus. She is a very nice woman; just learning how to balance work and Airbnb as she just started. She is also very willing to rectify and issues quickly and at your convenience.
House is VERY clean, including fridge, microwave, stove and oven. WiFi IS included. Location is ideal; close to grocery, Place de Versailles, restaurants and metro. Free parking on both driveway and street (very few places where this is available in Montreal).
I do recommend this place to anyone visiting Montréal as she is improving with each interaction and learning as she goes. Please be patient with her, she is a good host.
