Great location - the Colosseum, Trevi Fountain, the Pantheon, and Vatican City were all within a 25 min walk so we never used public transportation (besides the train to the airport from the railway station). Bustling area nearby meant a late dinner, fruit at the morning market, gelato, and pastries were a minute away. Notify in advance if you need the sofa bed, and notice the late check-in fee and the city's additional fees. Roberta kindly printed out my boarding pass in the middle of my stay which was a great convenience. There's a heating/AC system.
