Here’s a hotel with dual personalities: On weekdays it hosts business clients and some families, but on the weekends, clubbers pack the expansive terrace of its bar. It’s a good option for tourists who want to stay where they play. The structure began life in 1914 as the first poured-concrete building in North America and was a boutique hotel named for its architect, Joseph-Arthur Godin, until the Opus group purchased it in 2007. A late 2012 transformation softened the all-nighter ambience with improved lighting and more neutral décor, but sound still reverberates through the bedrooms’ concrete ceilings. For a quieter room, ask for one facing rue Clark.
