Roberta's flat - "Raul's apartment" - was a great option to stay during our 3-day stay in Naples. It was very clean and comfy, and the single space was just perfect for two people. It was close enough to the port and the historic centre, and also to Piazza Garibaldi, where the bus from the airport left us, so we had no need to take any buses or taxi and we walked everywhere from the flat.
We had a fantastic stay at Roberta's place, totally recommendable!
