Christina's place is fairly centrally located - it is walking distance to most sites, and a block away from a subway station (Flaminio), making the location very accessible to guests. The apartment is on the ground floor / garden level of a building, and just shares an entrance with two other apartments. I felt safe staying there as a solo traveler, and would recommend it for solo travelers only (the space would be pretty tight for more than one person). A couple cons to note: the apartment does have a bit of a basement smell and the shower is very small and prone to flooding the bathroom. That said, I enjoyed my stay at her place - it was decent value in a central location for a solo traveler, and she had nice touches (Kiehl's hair products, coffee machine).
