Stayed here with my wife and 2 children. What really stood out for us is how clean the apartment was and its location so close to the bustle of Termini (15 mins or less walk) but in a quiet area close to a supermarket.
The apartment's kitchen has all the conveniences required and the apartment easily sleeps 4 with additional room if you have additional guests.
The apartment has a real homely feel and the host is knowledgeable about what Rome has to offer
Would definitely recommend this apartment if you are staying in Rome.
