Portofino is forty minutes away and you can go if you want. Nobody here will.
Camogli is a fishing town that still fishes. The path from the house drops five minutes to a stone landing where you can swim off the rocks; the water is deep, clear, and cold enough in the morning to fix most problems. Fifteen minutes further along the cliff path is San Rocco, a church, a bakery, and a view that has stopped stronger people than you.
Walk the other way and in half an hour you are at Punta Chiappa, where Bruno has been pulling up nets since before Marta was born and will sell you anchovies straight off the boat if you ask him in the morning and do not ask him in August.
The house sits on the last private stretch of the path. Past the gate, it is pines, rock, and water. That is the whole neighborhood.
Camogli center: 20 minutes on foot down, 30 back up. Worth both directions.
