The place is in Corvetto, just 15mins from Duomo by metro. The neighourhood isnt the nicest to lookout at from the balcony but it is safe and without problems.
The flat itself is well equipped for the most part.
There were only two problems we had: no working lock on the toilet door and the temperature of the shower water would alternate between cold and hot at a whim. Both issues could have likely been sorted out by the host if we contacted them, as they were generally very responsive with my questions, but our party decided to not bother since we were not staying long.
To sum up, good stay
