Bello, pulito e perfetto!
Eduardo's place is very beautiful, just like in the pictures or better! Everything is richly decorated, impeccable and the ceiling is sky-high. It's right in the city center, close to all the main attractions and about 20mn on foot from the port and the train station.
The only thing we missed after 7 days was a washing machine but we knew it wasn't on the list of available options.
Obviously, it's the heart of Naples, so if you want a quieter (the apartment itself is perfectly isolated from the noise) and cleaner area - Posillipo is probably your choice but you'll be far from the main sights.
Therefore, if you want to see Naples itself this is a clear 5 star ++ location. Thank you Eduardo and Alessandro!
