The room was great... very clean and in a very accessible part of town (between the train station and the Colosseum).
However, check-in was very confusing. She made us go to a separate building to check in at a hotel, where they had a brand new staff member working who seemed very confused (I'm sure I scared that poor kid) and then he brought us over to her apartment, but didn't have the right keys and didn't know her apartment number... when we finally found it, she was already home.
Then she proceeded to try to collect an additional fee of $50 outside of what we had already paid through AirBnb. While she does mention a fee on the posting, $50 is still higher than what the total cost for 2 occupants staying 3 nights would amount to for a hotel occupancy fee, which I'm not sure is even valid to collect for AirBnb. She ended up waiving it because I was very flustered by that point, but it certainly had us concerned and made us think she was shady.
Thankfully we had no other issues and really the large clean room, bathroom, and central location made up for the issues we had at check-in.
She was very friendly for the remainder of our stay.
