Monica's place is spacious and well equipped. I stayed here for 3 days in the middle of my exploration across Italy, so I appreciated the cozy couch, kitchen, and laundry. I felt that I could completely recharge!
As others have mentioned, the location is in the middle of everything, just steps from a lively city center at Teatro Massimo. Yes, it can be loud, but with the windows and shutters closed, it's not too bad. I use a white noise app to sleep when traveling and it covered the noise fine.
I chose to upgrade from another place to this one, and I'm glad I did. The other place would have been too far and perhaps less safe. I felt very comfortable here, as though it was my own flat. A great choice!
