Wow! Our stay at Ernesto's pad was an A+ combined with a 5 Star experience. Wouldn't call it a dorm because its actually a lot better than that. He has nice and clean bedrooms with single beds as well as a room with two bunk beds. The apartment is big, airy, clean and very welcoming. Guest are actually considered as temporary organization "members" so you really get the sense that the home is your own. Ernesto invites members to use the kitchen, watch movies and just chill in the living room. There is a fine collection of art paintings and cool decor giving it sort of a hipster feel. The location is residential and not too noisy. There are restaurants at the street corner and it's a short bus ride away from Rome Trastevere train station (connection to major cities as well as FCO) , the coliseum and other attractions.
As per the host, Ernesto is the bomb. Extremely nice caring and personable individual that will try and accommodate your needs. He runs an organization "Together" with some buddies. Ask him about it, he'll be glad to inform you of it's goals and how it has impacted people though it's only in the early stages. The funds from your reservation will directly benefit Together.
In Sum: Great Host+Great Experience+Great Accommodations= Great Satisfaction.
Grade: A+
