Federico's place is conveniently located near the train station (Roma Termini) which is great if you're planning to take day trips to Napoli or Pompeii. Federico was very nice and helpful, and gave me plenty of privacy. His apartment is not only the nicest Airbnb i've stayed in, it's the nicest apartment i've ever stepped foot in. Little details such as, welcoming notes, advise, complimentary wine & cookies really added a warm feeling to my stay. Manzoni metro is a 2 minute walk away, as is the tram which goes past the Colosseum. This place certainly added a cherry on top to my holiday in Rome.
Ps - be careful not to use the hairdryer if the washing machine is on, it knocks out the power to the apartment:)
