Adrien has written down an incheck procedure. Make sure to read it, because the adres on airbnb isn't actually the real adres, you have to meet Adrien at a meeting spot because the apartment is difficult to find.
The neighbourhood is very cool: some bars and bookshops and generally a dynamic vibe. Quiet but still a lot of thing to do. The apartment however is a bit more like a hostel than an airbnb, so it's a different experience than a normally had with airbnb. It's really cheap so don't expect any luxury. This in itself is okay, the only thing that was a deal breaker for me was the bed in the yellow room: it's too small to sleep in properly with two persons and the mattress is rundown, you can feel the iron springs. The second night we put extra blankets on the mattress on top of which we slept, this helped a bit. The bathroom is not so clean. We didn't make use of the kitchen but it looked okay.
For me, it wasn't what I hoped for, but if the mattress problem is solved, it's a cheap hostel-like place to stay if you're travelling. Adrien was also easy to reach and flexible about check-in and check-out, which we appreciated.
