Excellent property in a superb central location - but no obtrusive noise from the busy street close by.
Regular bus links close by (download the atac TicketAppy app) although most places are in walking distance.
The in-person check process was smooth, with good communication via whatsapp - just keep in touch on check-in day and someone will greet you outside.
Baffetto pizza place downstairs was excellent, Frigidarium ice cream shop across the alley superb as was Da Tonino restuarant nearby for local pasta (50/50 locals/tourists on our visit).
If you want a beer but not the usual Peroni etc then try Drink Art Gallery, La Botticella pub - and a little further away, Baladin brewery. The Trastevere district is also worth a wander round.
