Although they claim to have had guests before, with all the disorganization we experienced, I had the feeling we were the first guests. The people we all dealt with were very nice, but getting clear answers(along with dealing with several people) was very difficult.
For the price we paid, this definitely was not in line with the property itself. Luckily we spent most of our time enjoying the city.
We will come back to Porto again, but will not rent this property.
