The best feature of Gioia's place is the location. It is 12 min walk from Roma Termini and 3 min walk from the Cavour station (blue line). Also close to a lot of the major attractions and a lot of restaurants nearby.
The worst feature is the shower. it doesn't drain properly and it is tiny. You'll have to shut the water off constantly to allow the water to drain before it overflows.
Overall not a bad place to stay for the price.
