This is a great budget option for Rome, VERY close to the Vatican Museum entrance, and very close to metro stations to journey further into the city. Everything was clean and comfortable. The WiFi and air conditioning worked great and there was plenty of hot water for the shower.
My only small issue was a bit of confusion about parking: I thought there would be free parking in the building, but the free parking only refers to street parking (which can be very difficult to find). There is a parking garage very close by, so it wasn't a big problem, but it's just something to be aware of if you are as foolish as I am and have decided to drive a car into Rome :)
Also be aware that there is a nightly tax that is collected in cash in person upon check in. This is something we experienced at hotels around Italy, so I guess there is no escaping it even with Airbnb... :(
Overall a great location and a great experience, highly recommend!
