In one sentence: not recommended.

Pros: central location; many restaurants and cafes nearby; flat looked exactly the same as shown on the pictures

Cons: In the beginning we would like to complain about the € 50 cleaning fees, as the way described about it on the website was quite misleading (“via Airbnb”, while the truth was we were asked to paid in cash secretly in the flat) and we were not sure if this behavior was allowed by Airbnb. But after all it was written there and could be explained in 100 ways so we would not argue on this too much.
And we did not want to spend too much time complaining that the warm water for bath would only last for around 20 minutes then we needed to wait forever for more warm water.
The biggest problem of this flat is, IT WAS TOOOOOOOOO NOISY IN THE NIGHTS. Before we decided this flat, we read in reviews talking about this noise problem and in the end after 4 nights in the flat, we would fairly say it was still above our tolerance range. After 12am, there were still people cheering and singing; before 7am, cars started to ring continuously. What made things worse was that the window in the room could not fully closed even with a plug.

All in all we paid nearly € 500 for 4 nights in the flat (440 in Airbnb + 50 cleaning fee), which is above the average cost for a room in Rome however we did not think we got the matching quality.
