Our stay in Christian's home was vey nice, he was very kind with us telling us what's the most important places to visit in Napoli and giving us an advice, eat a pizza in the best restaurant of the world, and so it is :)
The house was exactly as in the pictures, very confortable and next to the town centre, you don`t need to take any public transport to discover the city.
If we come back, we absolutely go there again.
