5 stars for excellent location (close to central train station and port), ease of streetside unit, privacy of own bathroom, quick responses of host, lots of provision shops nearby. Fried pizza round the corner is amazing! Do note there is NO wifi, but I did get a SIM card for data nearby for cheap.
But do note that 1) the neighbourhood is perhaps the oldest in Naples and doesn’t feel too safe especially for single female traveller like me. Yet I stayed 4 nights and didn’t meet with any incidents.
2) The unit is a traditional Neapolitan house with a corresponding door that was impossible to open for me. You need to turn the key and pull the door knob at the same time, I tried till my hands hurt and only succeeded 1 out of the 4 nights I stayed. Thankfully the host was very quick to respond and came to open the door for me within 3 minutes each time.
