We had an amazing 4 nights here, the flat is lovely, full of interesting books and music, with tea/coffee/jams etc. all available if we wanted. The room is clean and well decorated. There is a lovely balcony full of plants, ideal for a glass of wine before dinner. Santo and Silverio, Francesca's two cats are very sweet. Testaccio itself is ideal - I wouldn't recommend staying anywhere else; still has a great local atmosphere, fantastic restaurants/gelaterie/night life, very reasonable price with no pretence and just over the river from the beautiful streets of trastevere and a short walk to the views of aventine hill. Would 100% stay here again.
