The location of the Appartement is great. Very close to the cathedral, but most other sights are in walking distance as well. We stayed as a family with two younger kids and the apartment was a good fit. The kids shared the small bed room next to the living room and the parents took the larger one at the back. At night there is some noise from the bars at the street, but they didn’t bother us.
The highlight is the roof terrace. The view of the cathedral is nice. It’s safe for kids to play around and we enjoyed it during the day and for the evening.
