When we arrived at the airport, all we needed to do was to take a bus to the Central Station of Rome (Roma Termini) and from there it was just a short 10 minute walk to the accommodation. The location is very central making most places walkable with the Colosseum being about 13 minutes away and if metro is required, there is one just a minute away. There are plenty of supermarkets and restaurants nearby making it really convenient.
The interior of the flat is really modern. The place is also well equipped (other than the fact that we ran out of shampoo) and it also comes with a smart TV which you could use to watch YouTube and Netflix. The surrounding isn't exactly in a quiet neighborhood but it did not bother us at all.
The hosts were quick to respond to all of my queries and are really nice. They even provided guides and directions to navigate around Rome with advises on places to eat around the area.
