The room and the airbnb are very nice and very clean. The area is not the most beautiful but it has a very good connection by metro and train to other parts of Napels. Marica is very helpfull and will give you tips to visit.
The only thing is that its quite noisy, we had diffficult sleeping the first two nights because of the noise outside (it was weekend so there was a lot of car en people noise). And we had neighbours who watched television, since the walls are quite thin you could hear the television clearly. But after the two days it became better (other neighbours and no more weekend days :) ). Recommend this place because of the hospitality of the host and the good location to see Napels.
