Place was very clean and AC was such a relief in hot weather in July, which I can't comprehend. Overall stay was pleasant and Salvatore was easy to communicate.
As a side note, Vatican meusem entrance is 5-10 mins walk from the house (downhill) but walking back is bit more (uphill). In general, bus frequency and bus timings are not good in Rome (that's what I observed in some routes). Overall experience was great.
