Excellent location, very conveniently located. 20 mins walk to Notre-Dame Basilica, 16 mins to old port. There are a couple of pharmacies and a grocery store nearby 5 mins walk away.
Check-in process was really smooth. Mazen, the host, is very quick to respond to the messages.
The apartment in itself is well equipped has the basic necessities to spend a good couple of days in Montreal. The rooms are reasonably sized with very spacious wardrobes. Since the apartment being very close to the street, you may experience some disturbances due to the noises in the streets if you're a light sleeper.
Overall, this is a very good apartment at a very good location. Highly Recommended!
