We stayed at Luca's place in July 2018 and it was lovely. Walking distance to Rome Termini, nice and clean apartment. The best is that Nicole the co-host meets you at the station, to avoid the frustration looking for a place in the unfamiliar territory. She's very talkative (their superhost status is well deserved) giving all sort of tips you would expect from locals, ranging from nearest supermarket to nice restaurants and many others historic place.
One thing I would mention: in July stay away from Rome , overcrowded, very hot, makes it very unpleasant to walk looking for ancient historical sites
