This was our favorite Airbnb from our whole Italy trip, including one other in Naples. The location was very convenient from the central train station. We had an early flight so wanted to be close to the station to catch the alibus shuttle to the airport. The apartment is very modern, new, high ceilings, great air conditioning, amazing shower, clean. Manuel is a pleasure to message with, and was willing to meet us at an easy to find pizza place on the corner at the time we needed. Keep in mind, italy cities all do in person check ins so if you don't have a data plan make sure you agree on a time and location to meet. Without wifi this could be tricky.
That brings me to my only semi-issue with the Airbnb. The wifi is an iPhone with a data plan on hotspot mode. It's a little slower than some other Airbnbs wifi but the upside might be that you could maybe take the phone with you and have mobile wifi. Not sure though, so ask Manuel. We only stayed one night so didn't need to do this.
Oh, one more thing to help you if you stay. The open the door you have to turn the key allllll the way to the right ; and then when it stops, push HARDER to the right and the door will open.
This place is great though, you won't regret staying here! Thanks Manuel!
