Pros: Location was GREAT!!! Roma Termini station is a 10 min walk away, so it was easy to walk to the apartment. The Colosseum is also within walking distance, and there are many excellent restaurants and coffee shops nearby. The hosts were always very quick to respond and accommodated our early arrival time.
Cons: The apartment is on the ground floor, so it was a bit noisy at nighttime with cars and people walking by, depends on if you're a light sleeper or not. We had some issues with using the kitchen for cooking, but we only stayed one night so we never resolved the issue. I recommend testing the stove, microwave, etc. when checking in if you will be needing to use them during your stay.
Overall: Great deal for the price, we had 6 adults staying for 1 night and it did the job!
