Clean and well maintained apartment.
Great location: easy to reach the port if you want to go to Capri, not too far from the main station if you want to go to Pompeii, close to the metro station. From the airport you can take the Alibus to the port and then it's only a 5 min walk.
There is a good pizzeria near the apartment.
In winter it can be chilly in the apartment, but the air conditioning does the job.
The landlord is responsive and willing to help.
