The host was very quick to answer. Check in was contact less and COVID-friendly.
The room was a two minutes walk from The Vatican City. An absolute Perfect Location in Rome. 15 minutes from Sant Angelo and 9 minutes from the S. Pietro Station, so also with easy access to the airport. Check in was probably the easiest I have tried. No contact with the host. All is done online. However you must expect a bit of road noise since the road between the apartment and the Vatican has heavy traffic. However I think. All said this is quite a bargain;)
