I am a Computer Scientist and love classical music.
Angelika and her daughter Clara were wonderful guests. They through no fault of their own would up getting locked out of the apartment on their second night-! I had forgotten to tell them that the entry key from the outside was not the key used to get into the apartment at the top of the stairs. That knob had been locked so that they then had to wait over an hour for me and my husband to return home and unlock the door. Angelika kept her sense of humor and even offered to stay somewhere else if we were not able to make it in time.
We all were able to laugh about it again the next day- thank god! They were very understanding and kind, and left the apartment in great condition. I would highly recommend them to any other host!!
