The apartment is great, the location is excellent, the street noise is bothersome!
The apartment is very spacious and fully equipped to host a large number of people.
We are a family of 5 (2 adults, 3 kids) - we split ourselves between the 3 rooms.
The only big issue we had is the street noise (especially at night). 2 of the bedrooms are street facing and the windows do not filter any of the street noise. This was a real bother during the night, since every car/truck/person on the street can easily be heard in the apartment. Same goes for noise from adjacent apartments.
The internal bedroom (which is much smaller than the others) does provide a better option for sleep.
Other than that, all was great! The hosts were responsive and getting in and out was simple and easy.
As for parking - I suggest contacting YULiv parking ahead of time and securing a parking spot. The street parking in from of the apartment is free from 9pm to 9am (but you must move the car at 8am!). There are also 3 all-day free street parking spots on Saint-Cuthbert street (just around the corner) that could work as well.
