Just to cover the main points quickly: the host (Ketty) was great. Welcoming and accommodating about meeting us at a good time and showing us the flat. Also encouraged us to text her or email her with questions (which we mostly didn't need to). Arranged a car to take us to the airport (our flight was at 6:10am so this was the only smart thing to do).

Neighborhood also great: really convenient to standard Rome sight-seeing. Close to the Tiber, Trastevere, the Vatican, close to places like the Pantheon, Piazza Navone, etc. Also, on a nice street with nice strolling nearby.

We chose the flat because we were hoping for a view and we were really pleased with that. Glimpses of the river, St. Peter's dome, and lots of rooftops! It does involve climbing 92 steps. So you better feel OK about that. Three rooms: bedroom/bathroom/sitting room "downstairs" (but up the 92 steps). Tiny spiral staircase in corner and kitchen above the sitting room. Kitchen has windows on all four walls, and both the kitchen and patio (over the bedroom) have great views!

Decorated in a lovely way with interesting art. Perfect for us! Not perfect if you don't want to climb stairs, or if you have a problem with the low water pressure you would expect in this situation. Also, the bed was lovely and comfortable, but it occupies most of the bedroom so getting around the bed is a tight fit.
