Solveig was a wonderful host, the two-level flat is beautifully appointed, and the location of the flat is really unbeatable. Our one major issue (really the only issue) was the noise level; being a 300-year old home in the city center, the nighttime street noise (see also: drunk people singing at the top of their lungs) was a significant challenge for our family. Unfortunately, there was also another AirBnB group on the first level (this one is on 2/3) and they were socializing until the wee hours of the night, making sleep all but impossible.
If you are a heavy sleeper undeterred by loud noise, then I would not hesitate to recommend this apartment. However, if you need to sleep or you are traveling with light sleepers, I would encourage you to consider the trade-off between the value of your sleep and the cost difference/smaller space of a better-insulated hotel room.
