As the name suggests, this elegant B&B is a white house, as well as an architectural landmark. It’s on the corner of a tree-lined residential street in Montréal’s hip Plateau neighborhood, adjacent to Parc Jeanne-Mance, and close to shops on boulevard St-Laurent and avenue Mont-Royal. If the weather is cooperating, the organic breakfast is served on a breezy patio. Yoga instruction can be planned in advance. Rooms are spacious with antique touches, and many have claw-foot bathtubs that add to the homey feel. A growing reputation has attracted celebrity guests.
