If you are visiting Rome with the intention of sightseeing, you couldn't pick a better location. Everything within 10-15 mins from you. And convenient shops all around. It was in a safe area too which is rare when staying in the middle of a tourist centre. Would recommend to others.
Note: the hosts can offer many additional touches. We went for the airport run (nice cars, met at airport and the driver communicated with the 'check in person' to make it seamless - for 10euros more than using a taxi (where the set cost is 50euros). Also went for the breakfast which lasted our kids all week. The tour was very good too.
