The apartment is in a brilliant location - easy to get to the riverside, trams, bars and restaurants etc. (as long as you don't mind a few steps...). It's in an old building so don't expect double glazing, central heating etc., but it has loads of character and fantastic views of the river. We were there in early Feb so it wasn't super warm outside - in the apartment there are plug in heaters (and a wood stove, although we didn't use that) but if you're there at that time of year, take plenty of clothes (we didn't!). A very thoughtfully provided bottle of port kept us warm though! We didn't meet Joao but he was really quick to respond helpfully to messages beforehand, we didn't need anything while we were there. Porto is a beautiful and fascinating city and this is a great apartment to enjoy it from.
