This was my first AirBnB booking having heard good things about the process from many friends in the UK. One of my initial reasons was mainly cost as I am starting a new job in Vienna / Wien and there are a lot of expenses up front. However having experienced how smooth the whole AirBnB process is , especially with Siu Hing and Dina, I would not go back to Hotels even if I could afford them !! I am now in my 2nd place for reasons related to convenience and family but I would have no hesitation in recommending Siu Hing to anyone coming to Wien.
