Paraggi is very exclusive, known for having attracted celebrities and very traditional Italian families since it's surrounded by Villas and Castles.
A walk brings you to the famous harbor of Portofino (15 minutes on foot, 5 minutes with a lift) - this fine harbor, where grand yachts lie at anchor, where VIPs stroll along the promenade, where exquisite fish restaurants and elegant designer shops decorate the picturesque bay.
As always with Portofino, it is best to arrive with a large yacht. If this is not possible, take the train to Santa Margherita and then a taxi to Portofino. There is also a bus service between Santa Margherita and Portofino (travels in both directions, which runs every 20 minutes, depending on the season): Portofino can be reached from S. Margherita by bus in 10 minutes.
There is a ferry from Portofino to S. Margherita/Rapallo/5 Terre/Camogli/S. Fruttuoso. Water taxis are 100 Euros per hour. Pick up service at Genova airport can be arranged (about 100 Euros, reservation at least 10 days before arrival is required).
