We had the pleasure to be Guillaume's first guests. He was very nice and welcoming. I had to cancel my first night and he agreed, which was very accommodating of him.
The place is stylish. The neighborhood is nice, very safe, not very central but it is only a few minutes away from a metro station from which you can go anywhere. The second bed is actually the yellow couch which can extend itself. It was a bit small, so my friend ended up sleeping on the bigger grey couch instead.
