Location, location, location, plus a solid (in every sense of the word) hotel. Despite nice touches like a respectable mini-kitchen, the rooms aren't anything special, but being walking distance to not just the underground, but actual attractions (e.g., museums, Mont Royale, one of Montreal's several lovely cathedrals) on top of excellent dining options and Montreal's finest dive bar (Zippy's!) makes this a great base for exploring a wonderful city.
