We didn’t meet Sara but we definitely met Marco. It was a great stay and Marco was very hospitable. We needed to wash our clothes and they offered to give us some washing powder for the laundromat that is located a block away. The room was spacious, no tv but who needs one in Rome! Had our own separate private bathroom which was good. The flat has only few stairs which is okay and about 15-20 minute walk to Vatican City depending on pace. Ottaviano metro is close proximity. Best to have data to use GPS for first time. After that, you’ll memorise streets. Just follow Sara and Marcos instructions as that is what we did because we didn’t have data! Pleasant stay
