Great Host - communicative, thorough, accommodating, available. Left us some much appreciated snacks and water.
Great Location - short walk to Piramide Metro or Trams or just walk from there. The neighborhood is more for locals so I loved not having throngs of tourists.
Best Food - Right on the block I had some of my best quick food. A Roman style pizza place called Alice's and the unbelievable Gelateria Romano. For only 2.20 euro I got 2 scoops, melted chocolate in the cone, and topped with fresh whipped cream. Overall, Rome prices are cheap compared to Boston and the prices already include tipping. I hate the US when it comes to tipping....
Great Apartment - cleverly decorated, comfortable beds, airy, loads of natural light, very clean. Walk the stairs or take the tiny elevator.
