Very nice tiny/compact apartment!
And it even has two complete set of shower+toilet.
Splendid location in Trastevere, smack in the middle of Rome.
Be aware that for some time yet, possibly, (wall, not painting) renovation is ongoing.
Make sure to ask if it has finished - or that you don't care about daytime noise from machines and workers outside the two paired windows facing the backyard.
We did stay for one night and was pleased with the apartment, but not so in the morning.
Host and Airbnb fixed to get the whole stay payment returned. 👏
