Hosts are really nice and helpful, we didn’t have any trouble getting in touch with them when needed. You can feel that they care about the people they’re hosting. The room and bathroom was clean and sunny, it was a pleasure going back home after a long day of sightseeing. The location is good, we never used any metro the get to the city center, because it wasn’t that far and the walk was pleasant enough. Surely it’s not strictly in the city center, but still really good.
I can recommend Zhiang’s and Adam’s place when looking for accommodation in Porto!
