Carlo's house is located on the useful places in Rome, 10 minutes walking to Termini station and Colosseo. There is also typical supermarket at 5 minutes from flat and Metro station. The house is very organized for traveller and visitors from outside of Rome. The flat/room is quite clean and kitchen is very useful for traveller and there is also refrigerator to keep food.
Carlo also sincerely help us when we have any question about Rome and Roman's life. Therefore, I can strongly recommend to stay Carlo's house to stay in Rome.
