Pros: Spotless, Great location within easy walk to the Colosseum, Restaurants nearby, Comfortable, Quick responsiveness by the host, Taxi stand is less than a block away. Appeared to be a safe neighborhood (I'm a solo female traveler). Host was very accommodating allowing me to drop off my luggage early (while the cleaners were still working).
Cons: Tiny shower space, I had difficulty getting hot water and ended up with 2 of 3 days of cold showers. The host did respond quickly to my inquiry after the second cold shower. (The second day I tried letting the water run longer to attempt to let it warm up, but to no avail). It turns out that it takes 20 minutes for the water to heat up after the power to a tankless heater is turned on. The switch was marked hot water one the wall, but I was unclear if a circle or a line meant heat on or off on the switch. There was a lot of outside city noise including a bar 2 blocks away with many guys singing, even on weekdays (but I had the window open). I was unable to find the light switches in the hallways; twice I accidentally ended up ringing the door to another apartment; I gave up and used the flashlight on my phone to see. The host responded to all of my messages in Italian so I had to translate every message on my translation app which was slightly inconvenient.
Overall it was a nice stay.
