The apartment is on the 5th floor with elevator. Philippe was very communicative and the place was spotless. He arranged for keys at the entrance so I could arrive whenever I needed. Be aware of a spiral staircase to get to the bedrooms but it was not a problem for me. Very airy living area is fairly depicted in the photos. The bathroom is spacious and modern (shower). The location is excellent if you want access to the heart of the city. City busses were very easy and convenient to get to the convention center. I used bikes when I could but they often are empty or full for pick up or drop off, respectively.
Overall, a very nice and interesting experience.
