Diego has been very prompt in his informations for the arrival and is very helpful if you need some insider tips :-)
Poesia is a nice small apartment and perfect for a single- or couple city trip. You can reach it easily by foot from Napoli Centrale and you are right at the historic centre with all its small streets an typical italian scenery.
There is a certain noise level at night due to a lot of activity out on the streets (life happens on the streets in Naples), so you should not be noise sensitive :-)
