My girlfriend and I spent 2 days and 2 nights in the flat. The experience was nice enough.
The positives : the flat is clean and equipped with all the essentials. There are 2 small shops close-by and you are 10 minutes walk away from the metro, restaurants, etc. The eating options in the neighbourhood seem nice. We tasted one restaurant we would recommend. When we first called Tara, she responded quickly. The second time I called, she was busy and we ended up communicating by email.
The negatives: there is some sort of problem with Google, which does not locate the flat correctly. It would have been nice to receive a warning message. We ended up walking 15 minutes with our suitcases, which was a hassle. Both the aircon and the fridge are noisy. There seems to be something wrong with the fridge, which Tara told us she would fix if needed. The bathroom is quite small. If you don't have a car, going back and forth to the city center will take you about an hour, which is a bit long. The neighbourhood between verdun (where the flat is) and the city center is a bit dodgy.
All in all, the experience was enjoyable, though we would probably opt for another neighbourhood/flat if we were to come visit Montreal again in the future.
