Highly recommend the Cozy Nest! It is a perfect location - close to the Pantheon and Piazza Navona neighborhoods and less than a 2 minute walk to a major bus stop that can take you everywhere from Vatican City to Termini. Marlene was an incredible host - she gave us a local cell phone to use and stocked the fridge with a few things before our stay. She also called the taxi service for us and was quick to respond with any questions we had. My family is on the tall side so I would say 3 adults is a definite max. Thank you again Marlene for aiding our wonderful experience in Roma!
