What a charming apartment! We arrived a little late (no taxis at the train station!) but Guido was waiting for us and gave us a quick tour of the space as well as a review of the sights. His English is perfect. We'd reserved a room with a private bath outside our bedroom, but didn't feel any lack of privacy. The basement apartment is quite large with a fully appointed kitchen & dining room. This would be a great B&B to visit with a group of friends. We did have a bit of trouble locating a corkscrew, but we remedied that right away and left a new one in the kitchen. :). This is a very secure building with great locks on the doors and a safe in the room. The neighborhood is safe and full of energy at the nearby Piazza.
Our room was comfortable and had ample closet space. The weather was cool, so we never used the air conditioning. Our room faced the street with one street level window. There's not very much traffic on the road, so noise really wasn't an issue.
The location could not be better. It's a very short walk from the Forums, the Colosseum, and the Capitoline Museum. Just a bit further, but still a pleasant walk, will bring you to the Piazza Navona, Pantheon and piazza Argentine - a pleasant surprise and worth visiting to see the cat sanctuary. Guido recommended a visit to Basilica San Clemente and he was absolutely right, it's worth a visit and only a few blocks from the Colosseum.
from the train station this is only a €10-12 taxi ride, though you could walk it, if your luggage is manageable. A taxi to the airport was €48 and our lack if Italian was not a problem when making the reservation call.
