Don't look elsewhere. This was the perfect place to stay in Rome - not only is Trastevere the best neighbourhood, it's a 20 minute walk to the Pantheon, short walk to Vatican and Colosseum.
Luca's apartment is absolutely fantastic. Rooftop terrace is beautiful with views over Italy and the cathedrals. I can't fault it. The flat is on the top floor but he helped me with my bags which he didn't need to. Luca was generous, friendly, helpful and so accommodating.
I won't ever stay anywhere else when I'm in Rome. Thank you Luca!
