Ana has a lovely apartment in a well-connected area of Vila Nova de Gaia. She is friendly, responds immediately to queries, and very helpful. I definitely recommend staying with Ana.

The apartment is in a very nice and accessible non-touristy location, up a fairly steep hill from the port houses along the riverfront. This is a quick and easy walk for those with full mobility. A bus stop on all the tourist routes is only 1 block away for those who would prefer not to walk.
