Claudio met us on the street when we arrived even though it was quite late and was very friendly. A neighbour is on hand if you need assistance. The flat is on the top floor of a building in the quartetto espagnol, a lively 'authentic' area. We had no trouble at all, and spoke to some friendly neighbours, but I can imagine the area not being suitable for everyone. All the streets are noisy and incredibly active - kids playing, mopeds, horns, shouts, street vendors, which we were not expecting and really loved.
A short walk to Toledeo and the old centre, and the other way down to the castle on the docks, so it's well located.
The living room is more spacious than the pictures show. The bed was comfortable. The flat was perfectly clean and the decor was nice. The terrace is excellent. The wifi was patchy and there were a few details that could be fixed, but we were very happy with this flat and I'd recommend it to anyone who wants to stay in a part of real Naples.
