My family of 4 (my wife, 2 young boys) rented this flat for about 6 days recently. First off, the location is superb, just a 3-4 minute walk from the Roma Termini station. It became our central life line whether to use the metro, bus or to travel out of Rome. We also felt very safe there.
Our hosts Valerio and Cristiano made us feel very welcome with a champagne bottle, essential necessities (like tea/coffee/chocolate). The apartment is really well done and exactly as advertised right from the beds to the bathroom.
We enjoyed the company of Valerio who guided us on where to eat, what to see, best options in terms of price/cost etc whether it was pizza, pasta or the best gelato!
I recommend staying at this apartment in case you are in Rome. They are great hosts!
