We spent one week at these nice appart and we were very happy, that we had chosen this one. It is small but comfortable, very clean flat where you can find all the necessary things: from a lot of towels and plates to Nespresso machine :)
The disposition is perfect - it is not in so-called old town, so there live locals and it is very nice possibility to live like them.
All the sights are near the appart - you can go on your feet to all of them.
We liked to have breakfast on the big window sill, looking cathedral and have supper on the big antique table, looking for new routes.
Christoph, the owner, is very nice.
And you should choose this appart not only because it is wonderfull, but also because of elevator like from film "Hotel Grand Budapest".
