Lord Berri was the first place I stayed when I went to Montreal. All in all, I left without significant impression either way.
The hotel is located just outside Old Montreal - it's 3 blocks away from everything, and 2 blocks away from nothing. Rooms were small (as was the entire hotel, for that matter) but clean. Customer service was sufficient.
The parking garage is tiny and difficult to navigate - if you have a large SUV, or even a full size car, you might want to think twice about parking in the hotel lot.
If you can get a good deal on this hotel, take it for the value, but given you're in Montreal, I wouldn't pay more than around $100/night to stay here.
