This was an incredible disappointment for our family. We had booked two nights as part of our stop over in Montreal and were very surprised as Sandman is generally decent for low key travel.
There was significant black mildew in our shower, broken lamp bulb, wifi was inconsistent and needed constant resetting, our toilet plugged during the first use and continued to do so during our entire stay despite having maintenance unplug it twice. Also the room was generally musty and the air/heat had a strong dust odor.
The decent part of the hotel was a very well priced breakfast buffet that was fresh, hot and had plenty of fresh fruit included.
