We had a great experience staying at Roberta's apartment, just off Campo di Fiori. Roberta was accommodating and very communicative. She was also very accessible, responding to all of our questions before and during our stay. The apartment is in a great location on a quiet street right off a busy exciting square and within walking distance of all neighborhoods, sites, and restaurants. We would recommend this apartment to anyone visiting Rome.
All that said, I have two critiques:
1. We were charged 35 euro cash for a tourist fee. Rome charges a tourist tax to Air bnb hosts, but I believe the host should charge a daily rate that accounts for those fees and should not expect a cash payment that was not previously agreed to. Air bnb is cashless, and should remain so.
2. The apartment is exclusively used as a rental so it lacks some basic amenities (olive oil, sugar, non-stick cooking spray, tin foil etc). Alas, we simply ate out at many of the delicious local restaurants!
Again, Roberta and her place we're great - but I wanted to provide honest feedback on my critiques. I thank Roberta for a great time overall and recommend her flat to any travelers.
