The flat is very central, top location, it is large, with the view on the main tower but still in a rather quiet street.
We are healthy and fit (though with a baby) so it was ok for us to climb to the 4th floor. That said, it is not suited to people with health issues or reduced mobility.
The only one thing that we found really negative was the state of the kitchen. The dishes were all not properly washed so we had to re wash everything before use. Maybe a dishwasher could resolve this issue as it is very unfortunate…
Other than that both Ton and also Victor who greeted us were helpful and nice.
