My girlfriend and I stayed at Ezio's place for four nights and enjoyed every aspect of his Airbnb. His flat is located in Pigneto (the Artist District) and this area is filled with outstanding local restaurants and an excellent nightlife scene. Zazie nel metro, Ciak si Mangia (AWESOME FOOD), and The Gypsy Bar were a couple of the venues that we checked out during our stay.
Access to the city center is very easy via the tram (2 minute walk) or Pigneto metro station (7 minute walk to Green Line).
The flat itself is very cozy and roomy with a full kitchen, spacious bathroom and bedroom, and a full balcony that has a great view. If you are looking for a great value and to stay in more of a locale setting while visiting Rome then this is the place to book!
