Location is good, 20 min walk to the Colosseum and easy to follow directions. For other sights, would recommend taking a bus/metro. Not much in the area and quite loud in mornings/evenings with ambulance sirens constantly making noise.
Apartment 5 mins away from metro/bus and easy to find. Old style lift which added to the antique feel of the apartment. Locks were quite loud so could hear other guests coming in and out. Clean and organised inside, large bathroom with two basins. Toilet flushing is a little loud if staying in this room. Shower temperature does fluctuate between hot/cold when operating so have to be patient with this. Towels are not provided only a hand towel. Room is large although the bed is two singles pushed together and not a double (1 large mattress), this was fine at first but bed did start to shift apart. Lots of furnishings to place belongings. Room does have access to a balcony which was a plus. Please be aware that the listing does state access to a Kitchen however this is only to be used to make breakfast and non-smelly foods, not to be used to make full meals, lunch or dinner. Consider this aspect if you want to cook your own meals, as no detailed restrictions were stated on the listing rules.
Did not meet Cecila but she was very accessible via email/msgs and responded very quickly with any issues. Although could not have late check-out, she allowed us to store luggage in apartment due to evening flight and provided us with separate keys.
