I stayed at Emanuela’s twice on my way through Naples. The place is lovely, beautifully styled and immaculately clean. It’s well located between the airport and port (10min walk) and there’s plenty happening in the neighbourhood.
I stayed on a Friday night and while you could hear some noise from the bar downstairs it was not disruptive at all, and nothing more than the noise you’d hear from the street or main road.
Would definitely recommend and will stay again when in Naples.
