I wouldn't hesitate to recommend Giovanni's apartment. He was so helpful before we arrived offering to arrange a transfer from the airport. Eleonora met us at the apartment and was so helpful and friendly and recommended lots of sites for us to see and places to eat. The apartment was spacious and catered to all our needs. The location was perfect, literally meters from the colosseum and from the nearest metro-not that you need it as everywhere is within walking distance. Overall I highly recommend it and would come back in a heartbeat.
