I had a great time at Martin and Katja's place! The location is good, the apartment felt stylish, clean and safe, and the view from the balcony is spectacular. The hosts shared a helpful list of things to do and places to see in the area, including a recommendation for a local taxi service which worked out really well. Martin was very responsive to my questions. All in all, a great stay for work and I'll definitely be returning (hopefully for leisure next time).
