Dario- Thank you for being such an awesome host!!
I recommend his home to stay at while in Rome! Dario will answer all of your questions, quick to answer any questions and/or request! His home is literally next door to the Colloseum! The restaurants near by are good and all the monuments are in walking distance (bring your good shoes)- unless you want to catch the Metro (only a 2 minute walk).
I definitely recommend staying here!
