Great place, pictures are accurate. Great location, close to the Vatican and a 10 min walk to a metro stop. There is a very convenient coop just down the road for anything you might need/want to buy. Very secure, with three locked doors between you and outside. Very clean on the inside and AC was a blessing. There is a larger, well lit road close to the house that you can walk along home during the night.
Only negatives:
walls are pretty thin and we could hear other guests entering and exiting (we were beside the front door). However, we did not hear anyone else during the night.
The check in procedure involved calling the owner over whats-app to get instructions. Wi-fi is provided, however we could not connect to the Wi-fi from the outside door to call the landlord. Luckily I had a bit of data and the call lasted less then 2 minutes.
