I can highly recommend this place. Everything was fine and even a bit better than expected. It is the perfect place to discover the Centro Storico of Naples. Finding it was no problem at all. Just enter „Piazzetta Luigi Settembrini 55“ and your maps app will lead you right in front of the place (just across the street opposite of the Madre Museum of Contemporary Art).
The only downside is the communication because the host doesn‘t speak any English, but with Google translate everything went well.
