So, so good.
This apartment is super spacious and comfortable. We were three adults and were thankful for the extra elbow room. The apartment is well decorated and appointed. It is located in the heart of Rome, within close walking distance to Vatican City, Piazza Navona, Campo de Fiore & the Colloseum, to name a few important landmarks. We did not take public transportation at all while there.
The host is super responsive & provided a great guide with his recommendations. We would not hesitate to stay again. The only drawback - and it's minor and solvable - was street noise. However, we have white noise apps on our phones that we played all night and that drowned all street noise, including the pesky European ambulances.
