Marcelo was a great host. Clear communications, he helped us out above and beyond the call with a specific request. Apartment is nice, a great location and view in front. Be aware that, like almost all apartments in Portugal, it does not have central heating. Small electric heaters in the bedrooms suffice. We were there over New Year's and this was not an issue. Close to the streetcars and a grocery store, as well as the "main attractions" - the Port wine lodges. When you visit you'll get to exercise your legs a lot, Porto and Vila Nova de Gaia are both very hilly, and popular mapping apps don't do well with recommending walking routes as they do not take into account the altitude variations. But well worth the visit, and Porto is a great city.
