Silvano's place is great. I highly recommend it to anyone coming to Roma.
Location:
Its location is a short 10-minute walk to the Piramide Metro Line or Roma Ostiense (train line). The metro line will get you into the central area of Roma fairly quickly and it's cheap (€1.50), however, one can also take an easy 35-minute walk to the Colosseo and further on.
Room/Flat:
The room itself was very spacious and clean. There are two washrooms available, so one doesn't have to wait long if they need to use it. The flat is shared with four other rooms, however, it never felt crowded or loud. The room does face the street, but the area is quiet overall, so it didn't really affect my sleep.
Host:
Silvano is was a very kind host, offering to pick me up from the Metro Line when I first arrive and show me around the flat. As he drove me to the flat, he even gave me some information about the metro, places to eat, and some history of the area. He was easy to contact via WhatsApp or call, and there was not a language barrier.
