Our family of six (grandparents, parents, kids) enjoyed a relaxing, well-appointed stay at Nicolanna's apartment. She was an incredibly helpful and gracious host--staying up a bit late to greet us when our flight in to Rome was delayed, helping head off an issue with the air conditioning so we stayed cool, and providing thoughtful touches the kids and adults all enjoyed.
The apartment gave us the quiet, calm spot we wanted to siesta in during the heat. The street markets, food vendors, and markets right nearby were extremely handy. The Villa Borghese was a short walk away (the kids loved the fountains, bikes, zoo, and tree-lined pathways), the heart of Rome easily doable for the adults in foot, and cabs were easy to use to grab to come and go.
