Sabrina's apartment is a really cosy lovely place. It's a 15-minute walk to Vatican and the metro is right around the corner that takes about 15 minutes to downtown Rome. Close to the apartment, you can find supermarkets, lots of restaurants and just about everything you need. Sabrina is very accommodating and will go beyond if you need any assistance. Oh and last, she has two bikes at your expense, so that's a really nice cool touch if you want to explore Rome in a different way.
