We highly recommend this flat:
It is big enough for 4-6 people to live , and the flat is decorated in a beautiful Italish style and well equipped. WE enjoyed staying there.
The location is convenient for travelling in Rome. Very close to Termini and the subway station. If go to Colosseum, it just needs about 20 min walk.
There are some good restaurants and some groceries nearby.
Most important: Maurizio is SUPER FRIENDLY and NICE. We received a warm welcome and many helpful tips for travelling in Rome! Many thanks for his help!
