Overall, it was a decent stay. The host was kind and professional and allowed us a slightly earlier check-in time which we greatly appreciated as to avoid lugging around luggage in 40 degree weather. She responds very quickly and one can tell she cares about her guests and rentals.
The apartment itself is aesthetically pleasing. The location was decent- about a 10 minute walk to some good restaurants/cafes, but a bus/train/taxi ride to most of everything else in Rome. The host left some lovely detailed notes on transportation around the city, but we unfortunately found much of it was inaccurate, so don't expect 10- euro taxis from the airport to the BNB. There was also no bathroom amenities and we were only provided two rolls of toilet-paper (for 5 people over 4 days) with the rest locked up in a supply closet, so that was also a little unfortunate.
Overall, a nice stay.
