Traveling to Porto, you should visit not only the main attractions but as well walk around the lesser known quarters and alleys. For many visitors, this city has a mystical kind of appeal that is difficult to describe. This feeling varies according to place, time of day and most apparent to the light.
A lot of it can be put down to the inhabitants of Porto. They are generous and easy-going, like the River Douro and its heritage like bridges and monuments, the tiles, the balconies full of flowers and the lovely little and narrow alleys. The historic center of Porto, as well as the Gaia side, think of Port Wine lodges, are classified as World Heritage.
