A brilliant property in a perfect location! Four of us stayed at Afonso's place for 6 days, and we had a wonderful time. Our host was really kind and considerate, and took the time to give us loads of great recommendations, and showed us on the map the best bits of the coast to visit and how to easily get there.
It's in such a great spot - an easy 15min walk to the river, and we didn't walk for more than 10mins to visit any of the restaurants and bars we visited around the city. It's also super close to the Sao Bento metro and train, and near to useful bus stops, so we could easily take a bus trip to Serralves villa (a beautiful art deco mansion, with lovely grounds, museum, and a treetop walk), and metro to the Piscina de Mares tidal pool (amazing brutalist architecture at the beach!).
There was an issue with the downstairs shower and toilet, which the host was very apologetic and communicative about, and we just didn't use it for the last few days. However, this didn't really affect our stay as the upstairs shower was great. A lovely stay in Porto!
