Great location in the heart of Trastevere. Bedroom is quiet, from the living room you hear the bustle of the piazza. Bed is comfortable. Bathroom is a little cramped, not much hot water but in summer in Rome a cool shower is fine. Kitchen is quite basic. The apartment is quite dark and the decor feels dated and a little shabby. With a bit more love it could be such a nice place.
The host told me they would check us in in person. Then on the afternoon of our arrival, they changed the plan to a key safe. This was easy to use, but the host had promised we could talk about options for storing our bags when we met. We never met, so we just had to carry our bags all day after checking out. Acceptable option, but strange after being told there might be an option to store bags. Also I really needed an iron, looked everywhere and didn't find one, and the host wasn't there to answer questions and wasn't answering messages on the app - so I went out to our anniversary dinner in a very rumpled dress.
NB we were asked to bring our passports to show the host (who didn't see them, in fact), and €7 cash for the tourist tax.
All in all, apart from the stellar location, I'd say this place is fine but could be better.
