The biggest advantage is the Very good location, just behind the Vatican and 25 mins walk to Trastevere where you can find great places to eat and hang out.
The room was very small, but I guess there are other bigger as well. In the morning was a bit noisy due to construction work but for me it was not a big issue since I was awake at 8 am anyway. Wifi worked as well, which was helpful and I enjoyed my stay. Grazie!
