I do have two gripes worth mentioning. There is a daily city tax that is hidden deep in the policies, under house rules, after expanding the section, near the end of the listing. This ended up being an extra €28, paid in cash, for the total stay between my friend and I. It would have been a better approach to mention this in the main description or built into the cost per night. It felt odd to pay this in cash outside of Airbnb.
If you plan on walking everywhere, which we did, it's about a mile or so to the Colosseum and Roman Forum areas. About 30 minutes to the Termini Station. It's not in the most touristy part of town, which means if you are craving anything late night, you have to travel quite a bit for the night life and food. a myTaxi or UBER is going to be about €10-12 to get into the main part of the city.
She is still a great host, very accommodating, and gave us a nice place to stay.
