I absolutely loved this apartment. The location is 10/10, close enough to all the hotspots in the city, quiet, clean and very spacious. Alessandro is a great host, even if I did not have a chance to meet him in person.
The only flaw I could find was that the internet was shared with neighbours and at times it was too slow to even send a text message. I was told that the issue was a cable the previous guest broke so maybe it is worth checking with the host if that was fixed in case you plan to do any work that involves good internet during your stay.
Overall i would recommend this place, and can't wait to be back in Napoli
