Cool and stylish flat in the best location in Rome. Small but perfectly adequate kitchen with just enough for making coffee and simple meals, and a renovated bathroom with a really unusual exposed brick shower. Communication was great - you don't ever meet anyone (it seems to be an agency as there are four AirBnB flats in the building) but I had instant and clear replies to messages.
There are three short-ish flights of stairs, nothing impossible but the final flight is a bit steep and those with mobility or balance issues might find it slightly tricky. And be aware that the bed is in a loft under the rafters and doesn't get much cooling from the otherwise superb air conditioning - it might be too hot for some at the peak of summer.
