Overall this apartment suited our needs, Salvatore was a very friendly and responsive host, and we really enjoyed the location feeling more like a local. The metro is close and food options nearby are great. We appreciated the airport transfer.
As for the space, reiterating below perfectly summarized review by Austin : this is a very big apartment in central Rome, but it really needs to be updated and improved (the feeling of the interiors is circa 1970). The rooms are pretty dingy (peeling paint, holes in the walls, stained sofas, cheap furniture and random art that looks like it came from a charity shop) and the space isn’t very inefficient (it’s not a thoughtful use of space, so the result is that it’s not very comfortable).
It should also be noted that the two bedrooms share a door and a thin wall. The green bathroom's shower was not comfortably usable (and risky to soap up a tile floor without grips) so look closely at the picture of that if important to you to have 2 showers.
