The location is great, a short walk from either the Vatican one way or the life of Trastevre the other. Rome itself is a very walkable city and over the week we only used public transport a couple of times choosing to walk everywhere else.
I had to chase Donatella down to get check in information including contacting Airbnb when she didn't respond to my request for information at less than 72 hours before arrival. Once I did manage to get in contact she gave me clear information. Check in is a lock box but if you are arriving after dark please be aware you will need a torch to see the code on it because the street lighting is not enough.
Once inside there was a broken toilet seat which we were told would be mended during our stay, it wasn't. Also crockery & cutlery is very basic and certainly not sufficient for a larger group. With a bit of effort, this could be a five star stay but we didn't think it is at the moment.
