I highly recommend staying at Fiorella's place, for me it was perfect- 2 decent size bedrooms, nice modern bathroom, clean throughout and excellent garden/terrace area! I specifically wanted to stay in pigneto so location wise it was perfect for me (it's not the centre of Rome so check out the location before booking if that's what you are looking for, this place is about 15mins tram/bus ride to Termini station). Overall I can't find anything to fault, there was even a bottle of red wine waiting for me on arrival :) well worth the price. Will stay here again on my next visit.
