This international hosteling is perfectly located. This is a private room while the hostel itself is mainly dorms with whom you share the showers/bathrooms. The place is clean, the bed was VERY comfy, but what I liked the most was all the little universes spread through the hostel. A vibrant kitchen, cozy hamac room, a bar, a gym, a home theater...And that's not to mention how close we were from everything.
We were there for three days. The room itself is very small, it was hard for us to both stand up because of our luggage and the limited space. Walls are also very thin and that's the main trade-off you do for the lowest price.
All in all, if you're not a princess, this is a really good option if you plan on visiting Quebec and not staying a lot in your room.
