(I am resubmitting as I am unsure if my previous post went through)
We are a family of five and stayed here in late March, 2019. The apartment is superbly located. It is just a couple minutes walk to the Pantheon, and just a little farther to Piazza Navona. Also, easy walking distance to the Trevi fountain and Spanish Steps areas. There are lots of great restaurants and shops (gelato!) in easy walking distance.
The owner, Ginevra, is a great guide. We hired her on a couple of different days, and she guided us to colosseum, pantheon, forum, piazzas, etc. She is extremely knowledgable, nice, and her English is excellent. I would recommend hiring her, especially early in your visit to learn about the immediate area.
The apartment is nice, with two bedrooms, two bathrooms, a living area, and a small terrace. We had two kids in one room and one on the couch in the living area.
Overall, we loved staying here. It is a fantastic location and a very nice place to stay. I recommend it. Thanks, Ginevra!
