The check-in and check-out worked perfectly. And the location of the appartement is amazing. There is a bus just 2 minutes away but you can also walk easily to the center in 20 minutes. And nearby is also a bakery for breakfast. In the apartment we're also cooking utensils and a grocery is just 10 minutes away.
In general it was a perfect apartment for a short sightseeing trip and I would book it again!
