Luigi and Chiara were wonderful, kind hosts, who were really willing to help in any way possible. The flat is beautifully decorated, with great attention to detail. There is a useful file in the flat containing information about transport and the sights nearby - although some of it is in Italian, we managed with google translate to work out the gist. The wi-fi was fast and the washing machine and air conditioning were very welcome.
The flat is in a lively part of Naples and very conveniently located to the main sights – it is an easy walk to the Cappella Sansevero, Complesso Monumentale di Santa Chiara, the Duomo, the Napoli Sotterranea and the Museo Archaeologico Nazionale (and probably a few others, but that was all we managed while we were there). There are supermarkets also close-by and it was also an easy walk to the Port for ferries to the islands. Getting there was simple enough – it is only three metro stops from Garibaldi station, and then probably less than 100 m from the Toledo metro stop.
