Paul is very helpful because we changed our check-in time 2 days before our arrival. He is punctual and the check-in process is smooth and efficient.
The flat is beautifully decorated and exactly same as the pictures. The location is quiet, safe and convinent to reach the center of city (by walking around 20 mins).
I would say Caroline's flat probably is the best flat during my whole Europe trip (have been Prague, Hallstatt and Budapest) and highly recommend to everyone!
