We had really good time when lived in Frank's house,he helped us ordered taxi as we got Rome with late night flight,he waited us and explained everything which included how to visit Rome,nice restaurants close to his house(breakfast/pasta/ice cream),even told us how to protect ourselves when we are in Rome is not kind of dangerous as news!
Otherwise,Frank's house with really good location in Rome,the nearest station just with 2-3mins walking,with 10-15mins to the termini which is the mainly transit station is Rome,I was definitely recommended Frank's house is the best choice!!
