Italo was kind and flexible with the check in time, that was great because of our roadtrip through Italy. The appartment is in a complex with a small courtyard, a pleasant surprise! The appartment is small, modern and clean and has everything you need for a couple of days in Napoli. The balcony is really cute. The shower is very small (you could not see at the pictures) and also the mattress was smaller than the conversion (a crack of 10-15cm). But for two nights, the mattress was good enough.
If you are searching for a place to stay right in the middle of the old centre of Napoli this is a good base! Tip: bring earplugs ;)
