I stayed at Kate's apartment in July '17 with my family.
This apartment is fantastic. We have never had such a well-equipped, clean, cozy and simply marvelous place before. We wished we could have stayed longer.
Communication with Kate was without any problems and she even waited for us in the evening as we arrived late. She even turned the heating on before we arrived so that came into a warm apartment!
We can only recommend to stay there.
