Kind of unusual, and a little tricky to find the way in at first until you know, but a real hidden gem. The room was big, everything worked, and the location very central. Parking close by (sort of underneath). The area, like all central Ottawa the past few years, is really struggling to support the people that clearly need help for addictions or health issues, but this is as good a spot as you'll get and we didn't feel unsafe (though we had to cross the road once when someone who was really wired wanted to throw his milkshake into a restaurant or passerby).
The number one cool think about this property that doesn't actually change anything, but would make me want to stay there again, is the artwork. It's all by one (deceased) artist, and it's everywhere, in the stair wells, halls, different places. It's really cool, and one of a kind. Makes it from a good place into a special place.
