Casa das Virtudes was probably one of my favorite Airbnb experiences so far. The apartment is very stylish, comfortable and the location is simply unbeatable.
I believe we were one of the first guests and there were minor things that could be improved, like the cleaningless of the space and amenities offer. You should also have in mind that it's located in a popular street during the evening and there will be some noise until later.
I highly recommend this accomodation for a couple planning to enjoy vacations in Porto.
