The place is perfectly located within 20 min walk from the Vatican city!!!
It is also close to the Metro, which allows you to go everywhere else by train.
It is on the sub floor, so it tends to get a bit hot, but the host provides fans for all rooms, which makes it not as bad!
We were 5 people, including a toddler and the place accommodated us all with no issues. Host even went above and beyond leaving a portable crib and high chair for baby!
I would definitely recommend the place for others!
