I can really recommend choosing this one!
Domenico is friendly and responsive. Despite us arriving quite late at night (at around midnight), it was no problem at all. He also knows english well- I enjoyed that one chat we had one evening, about Italian cuisine :)
Room was really clean, bed was comfortable, and we also got a password for WiFi and our own set of keys.
The neighbourhood is friendly and safe, but I want to highlight that it IS a multicultural place, and someone not used to seeing a lot of people from other cultures may take a wrong first impression and feel uncomfortable.
The one and only complaint is that the neighbourhood can be quite noisy at night, but fear not- you can just close the window, the room has air conditioning :)
It was a nice stay, definitely worth the price.
