This was my first negative experience on Airbnb, unfortunately.
In a nutshell, this flat is essentially a business rather than a home, with an alternating set of hosts. For example, I never spoke or met Alessandro. The only positives are the location and the bedroom.
Communication with the host(s) is good, as long as you don't need anything or complain. For example, see all complaints regarding the sofa bed in earlier guest reviews - I can confirm that this sofa bed has still not been replaced, and is definitely unsuitable for anyone to sleep in.
Next time I am in Rome, I would definitely pay a bit more to stay in a space that is actually cared for, and not just created for lucrative purposes.
