Roberto was an excellent host. Our flight was late so he rearranged the car that he arrange for us. Then, he gave us a map and showed us how to get around, he was quick to respond to questions/requests during our stay, he also arranged a car to take us back to the airport at our request. The transport cost almost 60 dollars (50 euro) but the drivers were very prompt, well dressed, well mannered, and drove well. So, worth it! Overall, I would stay at Roberto’s flat if I make it back to Rome and I highly recommend the flat. It literally took 10-15 mins to walk to the Vatican and there were lots of places to eat and buy souvenirs along the way.
