Location - Excellent. Extremely central. We practically visited all locations on foot except the Vatican City and colloseum (which is again just a short ride by bus and can also be done on foot). Apartment is just next to piazza navona where we would walk to everyday after dinner. Grocery stores and restaurants are in same location.
Hygiene/cleanliness - excellent. Apartment was very well maintained.
Communication - Cate was extremely supportive as airline had lost our baggage. She helped with the delayed check in or check out.
Others- Apartment was on ground floor and that helped as we were carrying much luggage. The TV allowed to log into Netflix and hence provide more options. Wifi and AC were perfect as well.
It was a wonderful experience in Rome. I recommend the apartment strongly.
