Besides Madrid and Brussels, as mentioned below, there are several other cases.  Brasilia seems to the most populous with THREE living cardinals, one retired archbishop at age 80, the new cardinal-archbishop appointed in this round and a former archbishop who was appointed as prefect of the Congregation for Institutes of Consecrated Life and Societies of Apostolic Life and who is voting age.  In addition, there are two living Cardinals in Rio de Janeiro, one voting age and one not.  Westminster, England.  I know there are others, I just haven't taken the time to thoroughly investigate them.
