We meet Antonietta who was just finishing cleaning the room she could speak very little English so we got everything sorted out with the use of a translation app.
The room is in a very central place and at well under €100 which is an attractive price. Stazione Napoli Centrale is 1.2kms away and the room is not an easy place to get to on public transport without walking for a considerable distance, a minimum of 900m, more than indicated on Airbnb. So you might consider a taxi.
However if you decide on the cheap price you need to understand that you get what you pay for. Basically the room has an annexe with a single bed but is equivalent in size to a hotel room with a kitchenette. It is an interior room with no windows that connect to the outside of the building, so it's a bit like a cellar. Actually there is more lamp light entering the room at night than sunlight in the day. The room is noisy because it has a hollow metal security door which transfers any sound outside straight through and because of the nature of the old building that echo's you will clearly hear anyone entering the building, especially late at night, plus lot's of other random noises like rubbish collection or depositing in particular bottles.
The bathroom is by far the smallest we have experienced in two months of travel in Italy. Inside the shower is 60cm x 60cm (not all usable space because of the over sized concertina doors) which means if you are a large person you will find it almost impossible to shower. Don't drop the very small cake of soap they supply or you will never be able to pick it up without opening the doors and flooding the floor! Adding to the problem is a soap dispenser that no longer works, there are no shelves in the shower, the shower head is loose and the hot water temperature varies.
The internet, actually, is very poor I measured it's speed at 1.8mbps which is less than half of that required to run Netflix. This is not good when you realise that you're mobile phone has no signal in the room. The TV does not function properly and it has no free to air reception. The air-conditioning also does not work properly. We had it set at it's lowest temperature (16deg) but on our travelling clock which has a thermometer it showed our room never got below 26deg (which was the same temperature in the atrium outside the door). Beware if you rent the room in August the average temperature in the room rose to 26.5 during our 3 night stay!
On the plus side the room was relatively clean and the bed comfortable.
In summary; if you are on a tight budget or just need a central place to come home to at the end of an evening out this would be the place for you.
