We didn't meet Nela but she answered all our questions via email efficently. We really loved her flat, great style - the terrace is gorgeous & the air conditioning was EXCELLENT in the crazy heat of August.
Pigneto is a hipster area, a little rough around the edges but with super restaurants and bars. Lovely to unwind in after a hectic day sightseeing in Rome. It was an 8 minute walk to the tram or underground into the city centre which we found easy once luggage free!
