If you want to stay in the most hoppin' place in town, this is definitely the spot to get! You might not even get to enjoy it much considering that all the young people in Rome come here and the lines are long. But the place is fairly close to most attractions by walking, bus or tram so you can do some sightseeing easily.
The host communicated really well and we had a great stay. The place is pretty much as described and we had a lovely time pretending to live in Trastevere.
The noise issue is real, though, so if you're a light sleeper, this might not be the spot for you (though the hosts do try their best - there are ear-plugs in the nightstand and double-paned windows). The revelers in the piazza were not really the issue for us - the windows are enough to block them out - but the garbage trucks collecting the thousands of bottles left overnight at 6am on the dot in the wee hours of the morning (and once earlier on weekends too) for what feels like hours got to us every morning.
