Gisela's place is right in the heart of Porto. Very close to all of the main highlights and at a walking distance. The apartment has everything one may need and is very comfortable with very clean linen and towels. We were 4 people and two of us stayed at a sofa bed. The truth is it ain't that comfortable, but is good enough.
Gisela was very easy to reach and she's easy-going. She did everything she could to make us feel home. Definitely recommend this place to stay.
