I have stayed at many apartments in many cities and I never had a more lovely apartment or a more beautiful view. From the first moment of contact to the very last goodbye the landlady was extremely helpful as well as very charming.
I also particularly recommend staying in this apartment to anyone who appreciates the neighbourhood of tiny shops and genuinely neapolitan flair. The close proximity to the Quartieri Spagnoli and the harbour are an added plus. Also very close is the funicolare, one of the old funicular railways that takes you up to the elegant city area of Vomero and an amazing view over the city. Also the Via Toledo, one of the city's major shopping areas is only a couple of hundred meters away.
For the musically inclined there is also a very nice piano at the apartment just waiting to be played on.
