Gianni's apartment is really amazing! It is really near to the train station within 10 minutes on foot which makes it possible for the ones who take the train. Meanwhile, it is also accessible to the metro so that it is convenient to go sightseeing. If you like city-walking, it is a good choice to walk to the Colosseum cause it is not far from the apartment. Anyway, it is really a good choice to stay in Roma!
