Strongly recommend Gianmarco's home! I'll definitely choose his place when I travel to Rome again!
I'm a female traveler and alone. But the area is safe, even at 10/11pm. and it's walkable to every spot. The apartment is refined decoration and user-friendly at the same time. Mostly, Gianmarco is a really nice person and humorous. I tried almost all his recommended restaurants, they were really good! Breakfasts were included, in a TripAdvisor restaurant downstairs.
Probably because of the artistic style of the apartment, it attracts interesting travelers, I met some during my stay. We hung out together and had great time.
