Close to Union Station (15 minutes), so it was perfect for my stopover. It's close to groceries, St-Lawrence Market, pharmacies, public transport, lots of restaurants, downtown shopping. It feels like a safe enough neighbourhood. I was comfortable there.
The property itself is about average for a Canadian HI Hostel. Clean, basic, great staff. I was in an 8-person female dorm, there was enough space for everyone and their stuff. There were lockers, a bathroom and sink, hairdryer in the room. It wasn't one of the more charming hostels but really there's nothing to complain about except that the mattresses sagged.
