Cristiana's place was clean and as advertised. She even let us check in an hour early which was very nice! We never met her, but she was very responsive and gave us clear instructions on how to check in.
While the apartment was pretty clean, on the first night, there was a strong unpleasant damp smell in the room. However, it did seem to dissipate over the the next 2 days. The space is pretty small. I would say it is advertised accurately but we did not expect it to be such a tight space. The bathroom space is incredibly tight. The bathtub was very small and impossible to stand in, you have to sit in it. Can't say you'll get a comfortable shower here.
There were papers posted of rules everywhere all along the apartment like "Do not touch" "Do not drink coffee/wine in bed" "Do not use the dishwasher/hair dryer at the same time." While I understand the reason for some of the rules, it was not the most welcoming space to stay in.
The door is also pretty hard to open and takes a good tug and push. After a long day of exploring, the last thing you want to do is take 5 more minutes to get a door open before you can rest. Although she did give us instructions, it would have nice if she met us in person when we arrived to show us how to work the door.
Our experience here was fine, we have no major complaints, but would not stay here again. We stayed in other Air Bnbs throughout our Italy trip and they were much more pleasant than this one. It was good for the price, but we would recommend paying a bit more for a hotel or more comfortable space.
