We got checked-In by Dimitri, who guided us through the appartment and gave us Tips for the area.
the Appartment entrance is next to the bridge and the canal. (We were looking for the entrance in the street. :-) )
Everything is like on the pictures and even nicer. Everything is reachable by feet and near the appartment. All the restaurants have nice Gluten-Free options and allergic contents declared on the menu or even Gluten Free menues.
I would rent it again.
PS: I parked my car on the Parking, where they are asking you to keep the keys in the car, if they have to move it. Very strange for me, but it worked without any issues and perfectly.
