Awesome, spacious early 19th century apartment. Great location and great atmosphere. We really enjoyed the spaciousness.
The apartment has wooden floors and noisy hinges, so if someone in your company has a habit of wandering around at night, that won't be ideal. But beyond that the bedrooms are all in the back and very quiet and we didn't hear any neighbors. It's close enough to the center, although on most days we bought a family day ticket for quick access to other locations. Our kids (7 and 8) had a great time as it is an interesting and spacious house (probably less suited for toddlers with all the side tables).
Do bring your own leisure, as there aren't leisurely reads or board games (as a result did make the puzzle, for the first time in decades :'), there is only one piece missing). There are a few great guides present though and we weren't bored for a moment even though we stayed a week and the festivals were cancelled.
Definitely recommend this location. Did I mention already it is spacious and classy?
