Alessandro was very helpful and gave excellent recommendations. We were able to see a lot of Rome's monuments in a day thanks to his guide!
The apartment was very clean, new, and comfortably fit the three of us.
The location is surprisingly close to the coliseum. Ostiense is a lovely neighborhood that isn't touristy and has restaurants and grocery stores very close by. The bus stops are very close as well; it was about a two minute walk for my friends and I.
Trasevere was a bit of a walk as well as the train station but definitely manageable.
