Firstly, we only had interactions with Mario who was very friendly and hospitable. He was also very helpful, and doesn't seemed to mind our numerous questions.
Location wise it is more than 15 min walk but it is still manageable. We would recommend taking a bus there directly. (If you don't know what to take, call Mario and ask directly). Like some people said in their feedback, the place can get very noisy at night, depending on the situations. Mario offered us ear plugs when he knew there was road works going on. It won't be a problem if you're a deep sleeper like us.
Facilities wise, I would think that the photo and description is pretty accurate. We can't say much about the thin walls that doesn't reduce noise because we are deep sleeper. On a side note, we don't quite get how the heater works in Italy but it seems no matter where we go, it becomes cold in the night. And in winter, the room becomes very very cold. Mario did offered us a electric heater he was using though.
The kitchen is a wonderful addition where we get to cook our own meals and interact with other guest. It's a nice place to gather around and the kitchen has enough equipments for you to cook a simple meal.
