We stayed at Olivier's apartment for 4 days early July. It's a very nice comfortable apartment, spacious and easy to get to public transit and shopping. We only used the master bedroom, the bed was very comfortable. The apartment has good water pressure, nice audio setup, great TVs, nice kitchen, cute balcony off the kitchen for morning coffee/tea.
We could not ask for a better host. Olivier is very friendly, helpful, and responsive. We were 2 hours late to the agreed arrival time but Olivier was very understanding and accommodating.
We would definitely stay here a gain in our next visit to Montreal.
