SUCH A GOOD LOCATION! Across the river from the city center (pantheon, etc) and between the Vatican and Trastevere. It was super easy to get to all three points of interest. There are so many good restaurants in Trastevere!! Karen was a friendly, kind host and her apartment was lovely. Would recommend 10/10. Note that there is no elevator so if you have heavy luggage you might struggle a bit :)
