The air conditioning wasn't working, no one would answer the phone at the front desk. After one hour of calling a female worker answered and offered no explanation other than saying no one was there to help. Technician will be here after 9am. She sounded obviously frustrated however instead of being apologetic she seemed more dismissive. The next morning the technician came way after 9am, said he wasn't sure why it wasn't working but it should be working today. This continued for the 3 night stay. They sent me 3 squares of mini chocolate and a pill bottle of chocolate covered nuts. This was the most insulting gesture they could've possibly made. It was actually comical, it left myself and my family stunned. I expected better from Marriott even if we were in a different country than the US. It's why we choose the Marriott brand over others, for the service! July in Montreal with no a/c. I would not have been moved to a different room until the next morning which meant more inconvenience to my family. I'm not sure if the property turns off the a/c at some point in the day but being upfront with customers would have been the right thing to do. The room didn't have enough towels or toiletries either, those were requested around 7pm and weren't delivered until the next morning after calling again. I don't know if this is the normal behavior for this property and staff but it was very disappointing. Lobby is great, parking was easy but the customer service and room were lacking.
