Emma is a great communicator and responds very quickly. Her apartment is only a few blocks from Campo de Flori, 2 short blocks to a Main Street where many shops are and the #8 tram runs. It's easy to get to from the airport (commuter train then #8 tram). We never met Emma in person, her husband Alessandro picked us up from the tram stop, showed us the neighborhood, and took us to the apartment, gave suggestions on restaurants, and answered all our questions. He also took a picture of one passport, collected taxes (3.5 euro per person per day) and cleaning fee. The apartment is well decorated and spacious. The outdoor space (where the laundry machine is placed) is bigger than pictured. Kitchen is well equipped. Alessandro was very nice, he came over when we complained about loud music/roof party after 11pm and reported that to the police. He also came over when we couldn't figure out how to use the washer (door handle is broken). The wifi is good with strong signals. They allow you to take the wifi with you but the battery only lasts about 4 hours then it takes a few hours of charging before you have wifi again.
A few cons to mention: 1) the shower is small (about 30"x30") with shower curtain that would stick on you and the handle sticking out when you turn it on, which you'll surely bump into it when you shower. Depending on what time you shower, water volume can go strong to weak, hot to cold and repeat; 2) there were some weird noises, we think it's from the water heater. One sounded like dog whining, one sounded like hot air which goes on and off every 5-10 seconds or so; 3) think hard before you commit to a 5th floor flat. Are you willing to climb back up if you forgot something?... or need to use the toilet in a pinch?... or need a short rest before going out again? There are 96 steps to get to the apartment. If you are okay with all that, this flat is comfortable, at a great location, and the hosts are super nice.
