My partner and I stayed in this apartment for a week and what a fantastic place! The location is what really made this place shine. You are very central for walking to sites such as the the Pantheon, and the Vatican but the neighbourhood has a nice mix of non-tourist residential housing. This means that when you step outside the door you have the option of eating at one of the famous tourist destinations (such as Pizzeria Baffetto, 2min walk) or one of the local options (Italian only Menu, no website, just good food). After a few days of wondering around the streets you feel at home and nicely removed from the bustle of the tourist destinations. There is also a grocery store almost directly across the street.
The place itself is exactly as advertised, the photos are an accurate representation. There is lots of light in the morning though the windows face in internal courtyard. We found the kitchen well equipped to handle breakfast or a small meal. The bedroom and living areas were comfortable to accommodate a couple.
Barbara was also extremely helpful, and accommodating. We had a question about extending our checkout time after we had checked in and she replied via txt almost immediately, and extended it no problem.
Overall we would highly recommend this place for a couple travelling to Rome who want to be able to walk to the tourist attractions but also want a bit more of a relaxed (dare I say more authentic?) place to stay. It really is a great place!
