I stayed at the 4th floor. 3 days.
Cons:
My room was facing the street right over MCD. Tbh the stay wasn't very pleasant. There was so much noise from the construction all day long, got a headache from it.
Whoever designed the room obviously doesn't wash hands after using the washroom, the sink is outside the washroom, on the other side of the room. had to walk all the way to wash hands after using the toilet.
The temperature of the room was always cold - the heating wasn't working properly.
We had alot of luggage, we had to ask a few times to get somebody to get us a trolley. Btw didn't appreciate rolling the trolley ourselves - nobody bothered to help, we had to drag that all the way to the 4th floor.
Pro:
We called the service desk wondering if there was any microwave in the vicinity. To our pleasant surprise somebody showed up at our door with a microwave! (Within 5 mins) highly appreciated.
Good location for food and TTC.
I would say honestly pick a different hotel. I have stayed at few Marriotts. This one has been the worst.
