We really enjoyed our time in Naples! It was me and my sister.
Marco was nice enough to give us some directions before our arrival so when we arrived at the Airport, we take the bus to city centre. Then we had to walk for a while with all the luggages; but the weather was agreeable; so 20 minutes walk was not a big problem.
The building is located at the historical centre. We shared the house with a very nice couple, Philip and Yulia, who made our time in Naples even more enjoyable. You have a separate bathroom and every detail is included, such as washing agents and you are allowed to use the kitchen and there's a very close supermarket where you can easily find basic food and beverages. There al lot of "cafeteria"s and "pizzeria"s in the neighbourhood, which surely is an advantage of staying at the city centre.
You are not allowed to drive in the city centre, so you should prefer public transport.
a little reminder, no wi-fi :((
And at last, marco; you should definitely change the door number in the ad :))

Arrivederci!
