Qiang's place is great for those needing three comfortable bedrooms in LaChine. Six guests sharing one bath can be challenging but manageable if you all get along and work together. Qiang had milk, juice, bread, bagels, eggs and some other items in the refrigerator, and coffee was available - a nice touch so that we did not have to go to the food store right away.
We needed an extra towel, some hangers, and coffee cups. Qiang went to the store as soon as we requested these items and delivered them to our door. He was very responsive.
A few small items that would make the bedrooms a little better would be some hooks in two of the bedrooms and mirrors in each bedroom.
Given that there is only one bathroom, a nice addition to the apartment would be to put a sink in the laundry room / kitchen. We had to use the bathroom to get water and wash dishes, which added to the challenge of three couple sharing one bathroom.
Finally, be aware that there is essentially no living space. The laundry room / kitchen has a table and a few chairs, but guests do not have access to a room in which to comfortable sit and visit or watch TV. That would require an addition off the back of the house or access to the main living space, which does not come with this apartment.
All in all, it worked fine for the six of us since we were mostly out and about during our time in Montreal and LaChine.
