Massimiliano's apart is very well located in downtown and very well furnished. Getting in was really easy with no obligation to meet the person to get the key. Very nice light during the day and a perfect location to move around all the city. I discourage to take the car in Naples, but if you really need as we did there is a private parking at few meters but you need to call them in advance to fix the price as it' s quite confused and disorganised. As mentioned by most of the comments, even if at the 3th floor, the apartment is noisy due to the location on one of the main street.
Massimiliano was really nice and always available. The apartment is really recommended for a short stay in town.
