We had a great stay in Luigi's apartment. It's in a great location to explore the city, virtually on the sea front and a short stroll from the bars and restaurants around Castel dell'Ovo.

Luigi's mum provided a warm welcome (particularly once we figured out French was a common language!) and we especially loved the grand piano, although still not sure how Luigi got it in the apartment...

As others have commented, it is on quite a busy road, so pack ear-plugs. I'm 6'3", so the mezzanine was a bit low for me, but overall it was a great stay.
