The space is as described. The location is perfect if you want to go at night (and of course during the day) to check the S. Peter's basilica and the square. It's also near the Vatican museum and cheap local restaurants, like Borgo 139 (Italian sandwiches) and pastaciutta (Italian fresh pasta) both very cheap and affordable, especially if you're student like me.
The hosts are very accessible and easy to talk to, they reply really fast and are always available.
The only downsides of the house are the fact that it's near a hospital (if you have trouble sleeping, it's going to be difficult due to constant sirenes) and only one bathroom for 4 rooms (you may have bad luck with the remaining guests cleaningness).
Paolo & Daniela were amazing, if you go here you'll have a wonderful stay.
