I had a great experience while staying for some days on Carlo's room. He and his companion Eleonora are wonderful people, whom I quickly befriended and found empathy with. Theirs was a warm welcome that made getting to know them as pleasant as discovering the city.
Their house was the very first to be built in the Garbatella neighborhood, with an ample garden and an unique and creative interior full of books and trinkets from the couple's travels. The surrounding area is tranquil and quite interesting to discover, with a nice farmer's market, many traditional trattorias and superb 20s architecture. It gives an authentic feeling of roman life away from touristic areas while being close to the center, at about 3 subway stops from the Colosseum.
I would vividly recommend a stay here for anyone wishing to discover an interesting part of Rome while enjoying great hospitality.
