When we got to the flat we didn't meet Guillemette, but it was all explained to us before our arrival. She was always very quick on getting back to us.
The flat is in a cool area if you like multiculturality, nightlife and a dynamic environment.
You only to be careful about the staircase (6 floors without a lift). We carried lots of luggage and it wasn't easy. But if you're a sports person, it won't be hard...
