We had a great stay at Claudia's place during our first night in Italy. We were able to get there easily via bus and were also able to check in earlier--around noon. The place was as described and was clean and wonderfully located. We were able to walk to the Colloseum and Pantheon and there was a nice gelato place with 100+ flavors just around the corner!
As the listing mentions, it's on the fourth floor with no elevator so keep that in mind if you have a lot of luggage. It was a bit of a struggle for us but a good workout that made our forthcoming carb-binge more guilt-free!
