Pier's place was exactly as described, location is unbeatable. Having said that ,previous comments have talked about noise but this did not bother us at all, we slept every night and yes you can hear the noise from the pub from 10pm to 4am and then the garbage truck but we had no issues with this. And we stayed there Friday to Monday!
We walked everywhere, it is all maximum 30-35mins walk to Vatican, Colosseum and we saw all the local sights. All the food places recommended by Pier was also fantastic! Pier will happily arrange for private transport for you to get you from airport to the Airbnb but we opted to take Bus-Metro-Bus all for under 3euro for both of us just for a bit of fun and adventure. On the way back to Ciampino, we used the Free Now app and even at 4:50am, we had no issue getting a ride, flat rate of 30euro.
Some of our personal recommendation to look in to when you are bored with main sights: Visit Jerry Thomas Speakeasy, go check out Testaccio area and see the pyramid and Knights of Malta Keyhole. Ai Marmi Pizzeria in Trastevere is really good, thanks for this recommendation Pier!
All in all, we could see ourselves coming back to Rome again and no doubt we will stay with Pier again as we really liked his place! Thanks for everything again Pier! Ciao!
