The description is inaccurate (as of July 2022).
The apartment is definitely not 20 min bus ride from the city center. To reach any important landmark by public transit you have to travel at least 50 min and use 2 busses.
The apartment has no internet connection at all, so services like Netflix and Amazon Prime are not working on the TV. You can only use it to watch Italian TV.
The couch is comfortable but it is nothing like a regular bed. It provides uneven support under the head, back, and legs. The mattress however is pretty good.
Aside from that very good apartment, clean and pretty. If the far distance from the city center and lack of internet doesn't bother you I definitely recommend it.
