We stayed at Ortensia's apartment for 4 days and we enjoyed it very much.
Ortensia and Sergio as well were extremely helpful and accommodating.
Kitchen was well equipped and easy to use. Location in great! Tram 8 takes you to Piazza Venezia in about 15-20 minutes and from there you can take bus to different areas of the city.
Colosseum is a 10 minute walk from Piazza Venezia. Thank you Ortensia!
