Luigi, the host, is fantastic. He could not have been more helpful or friendly - any query I had was replied to really quickly in perfect English. His lovely apartment was perfect for our stay in Naples. Well equipped with everything we needed, everywhere was spotlessly clean and extremely comfortable. Check in was very straightforward.
The location is great for getting around on metro line 1 or using the funicular, it was so easy. Lots of fabulous coffee shops (VentiMetriQuadri is 5 mins away and fab), bars and restaurants (loved Osteria Partenope) close by and the National Archaeology Museum is well worth a visit (20 mins from apartment).
I wholeheartedly recommend this apartment and hope to return soon to explore more of Naples.
