This was my first Airbnb experience, we spent 3 nights at Federica's house and it was honestly a pleasant stay that I highly recommend! The house was big enough even for 5 people, it was really clean (something IMPORTANT to me), there was hot water 24/7, WiFi was excellent, the kitchen was fully equipped, the beds were good, the A/C worked perfectly. It is on the 2nd floor and there is no elevator but not too much effort needed to go up and down. The neighbourhood might get a little bit noisy during the nights because of the families that live nearby. Other than that I can't find anything negative to say.
Now, about the location you simply CAN'T BEAT that. You can walk easily north to the Archaeological Museum, south to the Castel dell'Ovo, west to the Riviera di Chiaia and east to Napoli Centrale! At first when you see the alley you might get a bit worried but trust me, there is no reason to do so, we didn't notice anythng strange no matter what time of the day or night we walked there. Pizzerias, trattorias, bars, restaurants, candy stores, everything is within 150m distance!
Check in and check out were great (we were more than an hour late upon arrival and Federica was waiting for us at the Dante station with a smile on her face), communication was great, good advice about Napoli, I don't think you can ask for more! Federica and her husband are such sweet people, we said goodbye with kisses and hugs...
Thank you for everything Federica!
