Location is good and close to the city via buses. There's a little store at the bottom to buy metro/bus tickets as well. Depending on the airport you're coming in from it can be either a smooth journey or take a bit long. That's nothing too major to worry about in that regards.
Raffaele is a funny and enjoyable host. Quite accommodating in fact.
The rooms could be cleaner- I had dust in mine under the beds. The toilet was also a bit small and hard to use with the flush broken in our one and only working after many failed attempts of trying. There are three different toilets altogether though so the other two toilets could be fine.
Kitchen had everything. Breakfast was good but very minimal. Its a small croissant + apricot juice.
There's stores for food nearby as well so you can cook easily.
Overall good experience but there are definitely things to work on.
