Located near the Vatican and castle of St. Angelo, walking distance to tram and metro. Neighborhood is nice, supermarket in the same street and plenty of places to eat/drink.
We didn't meet the hostess and were welcomed by a friend. Apartment is spacious and looks fine. The bed/mattress was pretty hard and the room was a bit noisy due to the passing scooters and ambulances outside. We were asked to use the other bathroom (not the one mentioned in the photo) but that wasn't a problem. The other bathroom has a bathtub :).
The hostess answered all of our questions regarding transportation and places to eat quickly via email. We had a great time in Rome!
