Diana was a great host, very responsive to all my questions about Porto and how to get places. she also booked us a wine tasting river trip that would of been fun but had to be cancelled due to river flow. Her friend met us and gave us lots of pointers for sightseeing. she also recommended some nearby resturants which was helpful. We loved Porto, all the beautiful tiled buildings, the river front area and the general feel of the city (a bit smaller and less hectic than Lisboa). I would recomment a visit.
