The host Luigi was friendly and easy to communicate with and met up with us upon arrival to give us a tour of the flat. It is located in an old but charming estate in one of Rome's most hipster areas and only a short walk from the train station. It was clean and tidy and had a small but fully equipped kitchen (which we however did not use as we had all our meals out) as well as a washing machine.
My girlfriend worked from home during the days and had no issues with the wifi. There does however seem to be other airbnbs / tourists in the building which could cause a nuisance depending on the other guests behavior and how sensitive one is to sounds. We could e.g hear people chatting on the street until very late (single glazed wndows) and people moving around in the flat above us (old wooden floors) as well as some kids playing and shouting in the stairways. It did not affect us too much; this is most likely the case in any older building, but it is worth being aware of if you are _very_ sensitive to sounds! :)
Thank you again Luigi!
