We stayed at Marina's apartment as 3 adults and 2 year old. It is a good base to explore Rome. Neighborhood is safe, not so much traffic. But still it is vibrant during day and night. There are many good restaurants, cafe and bars, these places are filled with locals in the evenings, you do not need to go far away for a good bite. We used subway to visit Colosseum (10 min walk to station), and bus for center (Piazza Venezia, 5 min walk and 10 min bus), and just walked to Villa Borghese in about 15 min. Close by, there are bakeries, supermarkets and a public bazaar...
Apartment is exactly as described in the listing. All appliances are working well. We found all the amenities we need. Place is tastefully decorated, a lot of paintings, objects, books and glass items but still easy on the eye, felt very relaxing after long walks in crowds. You feel like you are staying at a friends vacant house...
Lastly, Marina is a graceful host... She was very helpful before and during our stay. She gave us a big tour of neighborhood after she showed us the flat. After she realized that cradle was broken down, She arranged us a new camping bad for the baby just before we arrived. She was very tolerant when we told her that we broke some of the glass items of hers...
I strongly recommend Marina's apartment. It was a great experience.
