I was messaged by Antonio (Ciro's Son) and given clear instructions on how to get to the apartment, which was very easy from the central station. Antonio was super friendly and gave me lots of great advice on what to do while in Napoli (the view from Castel Sant'Elmo was incredible)!
The first thing I noticed about the apartment was how clean it was, very refreshing after a long journey. All the amenities were even better than expected, I cooked on the induction hob and it was better than my own one at home - it was small but did the job perfectly. Also there was plenty of other kitchen equipment which came in handy.
Despite being located in a very busy part of the city it was not noisy at night and I had no trouble sleeping.
Overall I had a really great stay in Room 21, I would recommend it to anyone travelling to Napoli!
