This apartment is amazing !!! I went with my parents and my daughter. And we had so much fun. The apartment is just a few blocks away from the Metro. You only need to take the orange lane to go to Old Montreal and Old Port (20 minute ride)
The apartment is perfectly clean and its really cozy.
If you worry(like I do) about bathrooms being clean, this option is perfect
It's in an old building but it completely renovated.
