Lovely, clean, spacious, good value apartment.
Only issue is maybe the neighbourhood isn't the best place to stay in terms of connection to the rest of Naples. Naples probably has the worst public transport infrastructure I've ever experienced in my travels and when you have a handful of unreliable buses it can be difficult to get around.
The transportation issues of Naples isn't really the fault of the host Lucia, but certainly a little more information around how the bus/metro system actually works would of helped us greatly.
That's the other issue. I'm not sure if it was because we arrived quite late at night (around 11:00PM), but Lucia and her sister gave us a very rushed introduction to Naples and the apartment which led to a few issues during our stay. The lack of WiFi really made it difficult to do any self guided research, so just make sure you look up how to get around first! We've passed on our feedback to Lucia and hopefully the welcome will improve for future guests.
Overall, our experience with Lucia was a positive one and we recommend staying here if you're in Naples if you want good value accommodation.
