We had a wonderful stay in Mathieu's appartment. It was clean, well presented and very homely.
There were a couple of small things to consider for future guests. We accidentally parked in the wrong carpark, we didn't realise there were two and didn't know which space had been allocated to us. Mathieu was very responsive and helped us to find the right place. The apartment isn't a true penthouse as there were lots of other apartments on the same floor and another floor above with the swimming pool which has beautiful views of the city. The sofa bed was alright for a couple of nights but I wouldn't want to sleep there for longer as it wasn't very comfortable. We also didn't have a key for the gym.
Overall we had a wonderful stay, the apartment is very well placed with lots of restaurants and bars nearby and a short walk to the Old City. It was really useful having the carpark on site as parking can be tricky in the city.
We would love to stay here again and would recommend to friends.
