Great location and Karin is a lovely, responsive host. The apartment has a lot of charm and would be good to host a small group of friends for dinner or as a base to explore the city. Lots of small restaurants and cafes walking distance. There are the usual city sounds but I didn’t hear loud music late at night or anything ridiculous.
The building is old and water pressure is weak, so the shower won’t invigorate you. And there is no elevator, so beware if you have heavy luggage. Other than that no complaints.
