Paula was friendly but her place was not a good fit for me. It is a guest house with a total of 5 rooms potentially rented to Airbnb guests. At the time I stayed it was full. There was a lot of noise from the people using the bathroom late at night, which was right next to my room. I went in the bathroom after another guest and found there to be water all over the floor - not sure how the host would mitigate this, but it was annoying. My room was drafty and cold at night and there is no heater. One odd thing for me was that the wooden floor had a lot of loose pieces so I worried I could have been disturbing other guests as I was walking around my room.
The room was clean and bathroom (before other guest used it) was clean. Paula provided tips on where to go in Porto and a map.
