"Overall, an adequate option to stay for a few nights to save money, which comes with trade-offs.
Advantages:
Half the cost of hotel options.
Close to restaurants, sights, and the O train for transit.
24/7 desk for help.
Mattress was ok -- better than expected for university residence.
Disadvantages (trade-offs for low cost):
Heating/cooling is centrally controlled. It was really hot in Ottawa and so cold in the room that I slept in a fleece top and fleece leggings with a blanket.
The toilet was flushing weakly and was partially clogged when I arrived. It would over-fill (not overflow) and then slowly drain. I left a note for housekeeping, but it wasn't fixed.
No amenities in the room that would be standard in a hotel like kettle, mugs, and hair dryer.
Evacuation: after a 12-hour day, I returned to my room and 10 minutes later, the fire alarm sounded. Everyone evacuated and we waited 30 min outside before we could go back in. I overheard on the firefighters' radio that there was no fire, but a lot of smoke from someone's microwave. You're sharing the building with students with evidently limited cooking experience and I'd now expect that such an incident is more likely at a student residence than in a hotel."
