We had a great stay in Alexia's apartment - it's spacious and very nicely furnished. The apartment is located close to Termini Station, we generally walked to most places but the nearest Metro station is less than 10 minutes away.
The apartment was clean and has everything that you need (I've seen a few reviews about a toaster but we wouldn't have wanted this in the 4 days we were in Rome anyway).
Alexia is a wonderful host and even very kindly made a reservation for us at a local restaurant for our first evening in the city. She responds very quickly to messages, and clearly cares a lot about her guests.
I absolutely would stay in Alexia's AirBnB again and would recommend to other visitors in Rome.
