Antonio met us at the metro station on Porto's busiest Saturday of the year - the music festival.
He took us to the flat and showed us round and made us feel very welcome. He told us about what there was to see and do in Porto.
He was available in person to sort out one or two small problems and contacted our host in Coimbra for us.
On our last evening he took us out for coffee in a hotel overlooking the city, where we discussed families, topical issues etc.
He was an interesting person and a real friend. I hope we can stay in touch.
