Spent one night here while attending the Women's World Cup in Montreal. We had a private room overlooking St Catherine Street which was always busy considering that there was a music festival going on. Thankfully there was an air conditioning unit in the window which drowned out the noise and made for a pleasant sleeping temperature. The room had hard wood floors and exposed brick which sets it apart from your run of the mill hotel.
It is very close to the metro line and walking distance to the Latin Quarter, Chinatown and Old Montreal.
Pro Tip: There is affordable and safe 24hr parking in the Des Jardins Shopping Center just down St. Catherine Street.
