We had a lovely time staying at Carl's flat in the Campo de Fiori area - an ideal location as we were able to walk to most all attractions in Rome. The flat is very clean, updated, and with AC. There are many restaurants and shops right outside along with the outdoor market during the day. Carl is a very responsive host who can help with most anything - from arranging drivers to and from the airport to restaurant recommendations. He is incredibly reliable and an excellent communicator. We would definitely stay at this flat or any other place managed by Carl.
