I visited Montreal for a solo trip on a long weekend - Cloud Hotel is close to the metro and is within walking distance to many attractions in Montreal. They send you check-in and check-out instructions well in advance of your stay, which I greatly appreciated. There is no in-person attendant to my understanding, which wasn't a problem at all for me during my stay. Cloud offers the privacy and most amenities of a hotel, and is good for those who want to get out and explore the city. I was satisfied with my stay and would stay here again.
