I am an Australian retired primary school teacher-librarian. My wife Margaret is still working as a nurse-midwife. We have done a lot of travelling with our children and even more since they've left home, but we've never used Airbnb before this trip. We usually prefer to travel independently but incorporate full or half-day tours sometimes. This trip is to fill in some of the gaps, and we have not visited Ireland, Spain, Portugal or Hong Kong before. We are non smokers.
