Maria was very friendly and easy to communicate with before we arrived. She arranged to pick us up from the airport (for an extra fee) and drive us to the apartment through Naples, which was actually very useful to navigate.
The room itself was better than pictured. Wifi worked well, lots of plugs, comfy bed. There are a ton of driving bus and snacks in the common hall / entry area that you can also pay for which is handy.
The location is good - perfect for sunny walks up to Chaia along the seafront.
My only niggles are slightly small towels (so plan to bring your own) and sometimes long waits for the shared bathroom - but that happens.
