I had a great stay. Federico's place is a little bed and breakfast, quiet and in a great location. Federico was very flexible and helpful. Overall, one of my best stays in Rome. I must also say I love the neighborhood (I use to live nearby many years ago.) It is very close to the Train Station, to via Nazionale and to Piazza Vittorio. It is safe, and you have the chance to taste cuisines from all over the world (or to get a good pizza at Pizzeria da Michele, in via Merulana.) My favorite places are the Indian Fast Food in via Mamiani, the Himalaya Kashmir indian restaurant in via Principe Amedeo, and Gelateria Fassi. I also like to go to Feltrinelli bookstore (Via Vittorio Emanuele Orlando) and IBS bookstore (Via Nazionale)
