Kathrin is incredibly gracious and very responsive. She will make sure you're having as good as stay as possible. The apartment is just right for one or two travelers and maintained cleanly so you feel like you're staying in a hotel.
I'm a light sleeper and woke up to the construction outside the unit. To Kathrin's credit, she was attentive to the noise; it wasn't much of a problem after the first night of jetlag and with ear plugs.
