Luca's place is well-situated near the major tourist attractions but not in an overly touristy area. A short walk gets you to the colosseum, Roman forum and palatine hill, and a 30 minute walk from the Termini - train station. We never felt unsafe in this area or apartment. Contact wasn't great as Luca wasn't in Rome, but had a contact in the building who didn't communicate very well. Our wifi shut off halfway through our stay which prevented us from contacting Luca at all, but he was very helpful when we could speak. The apartment is smaller than it looks but comfortable for 2-3 people short term. The bed is very firm and the street is fairly busy. Overall it was a good experience. I would stay here again.
