The place is fairly close to the Termini so, it's pretty central.
From a price/value ratio I think it's a great place. Plus, the host gave a really nice list of food joints and places to eat. That was pretty cool.
On a not so positive side, the place has 2 or 3 other airbnb rooms sharing a single bathroom. There is nothing wrong with that but just, you may have to queue for shower sometimes. It's not obvious sometimes when everyone wants to be early and avoid "queuing" at museums/monuments/tourist places, then your queuing starts at the bathroom...
Other than that, it's a cozy little place that is not too bad. Again, considering the price/value ratio it's a great deal!
