This listing is very accurate. We stayed here for about a week and it suited our needs very well.
The apartment is well-equiped and very clean. The kitchen had a full compliment of dishes, pot, pans, everything needed to make a meal. The location is nice, a quiet neighborhood that is close to sites, particularly the Vatican. Other sites are easily reached, as the bus is just a short walk from the apartment.
All communication was very prompt and helpful; that was much appreciated.
A few tips: Due to the vaulted ceilings and tile floors, noise from above can be heard; the neighbors above keep reasonable hours. I brought earplugs and was fine, but would recommend bringing them if you have a light sleeper in your group.
Also, the city tax is per night not per stay. Don't know why that didn't occur to me, it's obvious in the description, but I missed it.
We would stay here again and would recommend it to friends!
