Our experience with Andrea's place was twofold: on one hand the location -while a little far from Rome's main attractions- is really stunning near the Vatican and the surrounding area is really peaceful and safe.
However, communication with Andrea is not simple, he responds really late and while polite is not that helpful.
The main problem for us was the hot water. In the house instructions it sais that it lasts for 2/3 baths but we realised that it wasn't enough for even one: after 2 minutes it became cold as ice. Andrea was slow to solve it, told us after many attempts that he would come and while he says his coworker passed by, the water was working the same.
If he were to fix this (and answer more swiftly) we would 100% recommend the place.
