We had an OK stay at the Griffintown. First, you should know that it is in Griffintown So not downtown but adjacent to it. Steps from the Lachine canal and the western end of the old port.
The pros: The location is awesome if you like Griffintown (which I do). Getting around is relatively easy with frequent bus service but the metro (Bonaventure) is an uphill hike. Hotel is modern, clean, staff is friendly, lounge looked nice
The cons: The room, while large, is minimalist. Coffee but no tea. Two small bath towels. No robes, no hangers. Cheap cheap cheap!!! At this point, I don't think they can provide less, although the individual shampoo as opposed to the disgusting bulk stuff was a nice surprise. No breakfast service or restaurant on site, just a trendy bar.
We liked the apartment features like a fully functioning kitchen but the hotel part was lacking.
Would return only if we wanted to stay in the area, so for a summer trip, not a winter one. Hotel has a lot of potential --they just need to work on the little touches. And fix the big hole in the lounge washroom behind the door
