Natalia’s place turned out to be exactly as advertised (that shouldn’t be a surprise but it cannot be taken for granted). It’s two floors above ground floor, accessible with a (small) elevator, but the staircases should be doable for most as well (it’s what we used).
When we arrived, a person helpfully introduced us to the place and we settled in. One of the things we particularly like is the second bathroom: We’re traveling with teenagers and having two bathrooms really helps us get out the door and off to our daily adventures significantly faster. The place is air conditioned, which is highly desirable in August Rome. We also made use of the washer. There is no dryer but a drying rack worked for us.
Location-wise this is an outstanding deal: We were just very few minutes walking away from the Spanish Steps and the Trevi Fountain. However, many other places are almost as close: Hadrian’s temple, the Pantheon, Piazza Navona,... Even closer are convenient mid-range restaurants, and perhaps best-of-all is Caffé Lembo, a little hole-in-the-wall place that was exactly what we wanted for breakfast (great cappuccino and pastries; they have other items if you’re into that).
The neighborhood seems very safe. We walked it once around midnight and never felt at risk. The street is not completely silent at night, but the noise level was not a major issue.
Highly recommended.
