We stayed just one night but the apartment is great to stay longer as well! It is very clean and well equipped and very nice. Top location to visit Porto and to go for drinks at night. It was very loud at night because there was a student party close by, but Gisela prepared us and gave us earplugs. We didn't met but Gisela was very cooperative and easygoing - good contact, nice place - We would definitely come back!
