Very clean and pretty rooms. We slept excellently. The city center is about 20 minutes by foot. Christian and Maureen were very friendly.
However - caution - there is no free parking available! This was a pitty as this was one of our main reasons to book this appartment. We had to pay an additional 10€ per weekday for parking (and this was even the reduced price after the hosts booked parking tickets for us with their local resident discount). Communication with both hosts could have been slightly better (e.g., hosts did not reply to my text messages but sent their au pair to answer questions. The au pair, however, was not really informed about e.g. parking conditions, house rules etc. so some questions remained unanswered)
