Cristian is an excellent host.
His apartment is just as represented on Airbnb. It is very spacious and completely updated - yet retains that Roman charm. The patio is a rare (in Rome) and wonderful spot to escape from the hustle and bustle of the downtown tourist spots.
The bus stop is convenient to the main points of interest by taking the 60 line to Plaza Venezia or the 90 to Termini.
From there a short walk or any number of connections take you wherever you would like to go.
I highly recommend Cristian’s apartment for your stay in Rome.
