Hôtel Griffintown is in a great location, pet friendly, modern and very clean. We enjoyed our stay and found the staff very helpful. It’s great for long term stays because it has kitchen, washing machine, etc. Essentially a small condo.
A couple things to note - the parking is pricey ($38/night + tax). There are other, less expensive options in the area. Also, despite « hotel » in the name, they do not seem to offer daily turndown service. Which was completely fine for us, but just something to note if that is something you prefer.
With that being said, the desk staff are available 24/7 if you need anything at all. I would recommend this place.
