Great location next to the Vatican, the castle of Sant'Angelo and the bars/restaurants by the river.
Bus station right in front of the apartment, although we just walked everywhere because we like exploring and in our opinion a 10-20-30min walk in Rome is fantastic.
We were in touch with Martyna and she gave us great advice as to places where to eat (and also where NOT to eat) and visit. She is very friendly :) She recommended Sabaudia beach 2hrs away from Rome and so we went there and it was great and safe ! Also the best pizza we had was in the countryside near that beach.
I recommend this place :)
