This was a good choice for us, as we were traveling in a large family group with small children.
It's in a small but very cute private building, with private entryway. The building has a small elevator but the apartment is just 1 flight up so you really don't need to use the elevator unless you have health problems. The bedrooms are cute, 2 of them have bathrooms within suite and 1 has the bathroom in the hall. Two of the bedrooms have a tiny balcony facing the sidewalk. The neighborhood is very quiet and safe, our first night there my husband and I strolled down past Vatican City, past Castel Sant'Angelo and along the Tiber. We were out well past 2 am and felt completely safe.
The only downside to this place was that the electricity tripped several times when whenever we used the iron, and also that the bedroom door latches didn't engage so privacy was an issue. It isn't near any "hot spots" but there is a bar/cafè across the street and a restaurant just a little walk away that was really great and had great service. The bar across the street also serves American style breakfast in case you get tired of the Espresso & Cornetto breakfast.
