Really lovely little flat with lovely views from the balcony. It was well equipped and also had a helpful selection of guide books. The streets between the flat and the river are scruffy but very lively with lots of people about so they are safe.
There are lots of restaurants to the south of the flat [which were very busy - you might need to book] and also lots along the river [down the steps]. The location is fantastic for exploring central Rome on foot - we didn't bother with buses at all.
