To say that Chiao-Hua is a wonderful host does not even begin to describe the extent to which she & her partner care about their guests. The reservation, and the whole trip to Vienna, would not have been possible without their assistance, willingness to provide additional documents to secure a visa, and being good natured about it all along. Chiao-Hua is a dream host; the city of Vienna should award her some recognition for ambassadorship! Kind, welcoming and generous hosts one is lucky to encounter. Thank you.
