Andrea is extremely welcoming and knowledgable about Rome and top places to visit depending on your interests. Definitely ask him for recommendations. We visited Via Appia Antica, the oldest road in Europe as we were keen for a walk and learning about the history of Rome on a budget. Andrea gave us breakfast as well. The location is a bit further out but we bought 48h travel cards (about £10) and used the train to quickly travel into the centre as per Andreas recommendation. Really enjoyed our stay and keen to visit again soon.
