Great communication with host. Always happy to help and provide assistance. Excellent location specially if you want to visit Vatican City. Quick and efficient access to metro.
The only two points I would mentioned are:
1. There was a bad smell coming from toilets and shower. but i believe that this might be due to the cities water supply rather than the apartment. one of the showers was clogged and would accumulate water (it wouldn't drain properly)
2. The lights were not working in on room and the switch would control lights from other rooms.
