We visited Montreal to attend friend's wedding, and we wanted a place that is near downtown, and Guoying's was the best place that is right downtown and in the a reasonable price range as well.
The place has all the necessary amenities u would need, nice rooms with comfy beds, a nice spacious living room, and beautiful balcony over looking crescent Street with all its bars and pubs.
I would definitely use Guoying's place again for my future stays at Montreal.
