It is a lovely place in an amazing location. The apartment is very spacious, clean and modern, just like in the pictures. I'd recommend it for a short stay to get to know the city. Most of the sights are within a short walking distance: there are plenty of bars, restaurants and cafés very close by. Also, there is a little shop where you can get some convenience food right across the street and a big supermarket in less than 10 min walking distance. The equipment is rather basic (no cleaning supplies, very few kitchen items, no iron etc.). It's on the 4th floor- the view on the cathedral is very lovely but you have to take into account that it's an old house without an elevator.
Organisation/communication is definitely something to improve on in the future, but overall I was satisfied and would consider booking the apartment again because of its convenient location.
