Car: not necessary
From the port of Capri take the bus to Anacapri. Go to via Orlandi and then turns on the left, when you sea the red house (foto). Yo can also take the cable railway to Capri and the a bus to Anacapri.
I suggest not to go to Capri by car, expecially in summer. It's very difficult to find a private garage free. It's better to leave the car in Naples, if you have it.
Near the house there is a good restaurant-pizzeria: "Le Arcate". At Blue Grotto restaurant "Add'o Riccio": good fish!
If you want to go to mountain, from Anacapri there is the cableway to Monte Solaro. Nice trip, on foot, from Faro to Blue Grotto, with suitable shoes.
Wonderful promenade: "La Migliara" to see also Faraglioni, very good restaurant here.
