All the good things first: the host was very helpful with rental car locations close by and dinner ideas in the area. The apartment is very spacious! The location was perfect. The neighborhood is very nice. Metro station only a 5 minute walk.
Some items that could be improved: the apartment needs to be treated for ants. This was a constant battle. While the reservation indicated 3 people would be staying, only 2 towels were available. I did find a 3rd one I assumed was clean in the dryer. The air conditioner which we really could have used for the last two nights was missing the second battery to work the controls.
We really enjoyed Montreal! Beautiful city!
