Lisboa smells good !! - a line taken from an old song ....
The Portuguese have an almost natural affinity for Lisboa. They will go there on a day trip to see friends, visit 'at the drop of a hat' to do business or visit a favorite doctor. Others, mainly the younger ones, will go here for their university education or to see international artists and spectaculars.
Some, being the more wealthy individuals or families, might have a second home in or near the city. Or maybe a primary home in the city or nearby with a second home elsewhere.
Whatever your reason for going to Lisboa or staying over in the city, do have a wonderful time!
