If this is the district you are looking to stay in then the location is good as it is right next to metro stop. Easy 1km walk to Tiber and to Vatican. From there, on foot, you can reach all destinations to see with ease.
Apt Pros: Renovated with 2 bedrooms each with own bathroom. New windows with shutters to block heat and sun and nice working AC. Beds are hard but relatively comfy. Washer is new as are all the appliances. Has a Nespresso machine but no pods so bring some if its your first morning without shopping. Building has elevator and a great little snack, bar place below for pastries. Small but efficient layout. Not really a balcony to sit but nice to have outside view even for airflow. Interior of building so less street noise.
Apt Cons: Not really the hosts or apt issue but construction on apt above which begins everyday at 8am (banging and scraping etc) so not easy for late sleepers. Rome is loud and a few nights the street noise is there and may prevent you from getting a sound rest. The apt has two showers but if you are of a large frame you will not fit in the smaller master shower. Issues with hot water, lots of it but it was not regulated, super hot then super cold without touching dial..frustrating but small issue.
Host is wonderful, kind, helpful and even delivered extra pillows at 10pm at night. This apt is great value for the $ as I have stayed 2 blocks away on a prior trip and paid much more.
