Location is great if you want to visit vatican city! It is 20-min walk away. You still have to take a bus to other attractions/heart of Rome so isn't that convenient but there are quite a few buses you can take!
The only gripe i have is that the toilet was poorly, you can't shower without making the entire floor very wet and then there is barely enough space to change cos the hooks where you jang your towel are in front of the toilet bowl and there is not much space there.
It also gets a litttle noisy at 6am as there are pre-recorded announcements (i think from st Peter Square) going on but at least it is quiet at night!
Host is responsive and was kind enough to do me a favour - letting me store my baggage for 2 hours after check out. Thank you!
