Great apartment right downtown. It allowed us to easily explore and get a feel for Naples. You are walking distance, or a short taxi ride away from restaurants, shops and local attractions (crypts, castles, Pompei, art museums, etc..). The burger/butcher shop right downstairs is amazing.
The house is well presented, very clean, and with great wifi (kids were very happy). We were there in the middle of summer so it was a little bit warm and you are right in the centre of town so there is a bit of street noise- but nothing unexpected.
If you want to feel like you are staying in Naples centre then this is a great choice for an exciting and action packed city break.
