For me Barcelona easily wins of Melbourne; no idea what the criteria of most livable city is; streets littered with homeless, completely dead nightlife during the week and only average during the weekend (and I am 44, so I am not looking for much but even that is not there) and expensive. Barcelona or Lisbon are a lot nicer imho.
