Impeccably clean house! He was very detailed and attentive to our needs and we got breakfasts for the two mornings we were there and even woke up extra early because we had to leave early to the airport. We also took up his return airport transfer offer which was reasonably priced. As for the location, it is not exactly at the center but it is accessible via public transport and you can reach the Colosseum within 20minutes in a bus. All in all, I highly recommend his house to anyone that wants to stay in Rome for several days. Thank you so much for the hospitality, Sergio. Have a great day!
