The location is fantastic!
The appartement is great, but does show signs of use, not reflected in the pictures.
Some minor issues, like the bathroom lights taking 15 seconds to turn on, and no pan in the kitchen were unfortunate.
We were also unfortunate enough to be in the appartement on a night when the heating-pipes needed "venting", so there was quite some noise during the late evening / early night. Jens was polite, and quick to respond to messages, but unfortunately couldn't offer any solution. It may be just a few days a year, but we happened to run into it, and that is reflected in the 4 stars, instead of five.
Will still recommend the appartement if you need something central, near the train station.
