Thank the host for providing us a nice apartment to stay😊 There are some suggestions.
Maybe the host could tell the guests about the “cleaning fee” (40euro) before they place the order.
The location was ok, but not very friendly to walk to the sightseeing places. Some tips, if you take bus 870, bus 982 or bus 44, which may take you to the Colosseum or Vatican, they run every 40min at least in the morning (we went to those places around 7:30am). The buses tend to be less punctual. Tram T8 can take you to Piazza Venezia, then you must transfer to another bus to the Colosseum.
Those are the tips we have for the future guests.
