Had no problem communicating with Concetta from the moment we landed at the airport. Our luggage was actually misrouted to the Paris airport, we were able to provide Delta where we were staying and gave Concetta's phone nbr to them. She was able to calls us and provide an arrival time for our luggage to the Airbnb, that was very helpful. There is a guide book that she provides that has information and instructions how to get to the tourist sites. The bus and train (Metro) system in Rome can get you anywhere you want . Metro is about 11 minutes away, and the bus to the Colosseum is very close to the apt. You can also reach the Colosseum by Metro..We preferred the bus, because you can see the city more.
Once at apt Concetta is there to greet you, and tell you all about the tourist sites, transportation, places to eat and local supermarket. She is a great host. We were there in JAN, the only drawback is the apt does not give much heat.
