Le Clizie's place is possible the best location to stay in the whole of Rome. It was central to pretty much everything. Situated just in front of Campo Di Fiori (vibrant square with great nightlife). We didnt need to take any public transport to any of the touristy places.
Her place is clean and quiet. She provides a lot of useful information upon arrival and also plenty of food and beverages.
I highly recommend Le Clezie's place for a stay in Rome.
