Elisabetta's apartment is situated in a great location, Trastevere which is close to ancient and historical centres of Rome and is itself full of historical/cultural hotspots in addition to restaurants where one can taste authentic Roman cuisine.
The apartment is part of a character and stylish 18th-century property, making for great ambience in a city as eternal as Rome. It is also quite comfortable and well heated during the winter (January 2019). Unfortunately one of the downsides of such buildings is that renovation efforts may fall short of modern health and safety standards: the stairs to the mezzanine and the shower/tub came across as unsafe, not so much to me as to my mother who is elderly and has impaired mobility. Overall a great experience though and I would recommend the flat, especially for younger travellers.
