The location of the apartment is so special because its near to Colloseum.... The only better place you can get could be the Colloseum itself if AirBnB has a vacant place in it ;-) ...
The apartment entrance represents the ancient Rome and also has all modern safety features... There is a good pizzeria and bar in the same premises which is also good.....
Listen to instructions given by the owner for using the showers and bath tub... Its important to know as otherwise it could get complex and you may end up in frustration... As such there are no issues with them but operation is not straight forward....
We were in peak summer on the hottest days in Rome and the A/C was perfect help for us...
Kitchen, Dishwasher, Washing Machine were adequate. Apartment itself can comfort 8 adults easily.
Last but not the least, during check out, since you will Leave the main keys in the house itself, please know that there is an intercom key that you need to use to open the ground floor gate... I am not sure how this works for a single tenant... But you need to make sure there is one who opens the main door...and another keeps the door open until everyone leaves the building...
