Ana and Tiago's apartment was one of my favorite on airbnb. It was exactly as pictured, immaculately cleaned, and with minimalist decor. I loved the porch/dining room, which also hid the kitchen, a very tiny, but still functional space. We cooked a delicious risotto, but I would recommend eating out anyway, as the food in Porto is delicous!
We visited during a heat wave in August, and kept the apartment cool by leaving the shutters closed during peak sun exposure.
The apartment's location is top notch. Everything is walkable, and there is easy paid parking on the street (we parked right in front of the apartment for our entire stay).
Ana and Tiago were out of town upon our arrival, but their friend met us and showed us around. After we checked out, my partner realized he had left his ring behind. Ana was so sweet about it, and she was accommodating enough to return it to him immediately after he realized it was gone.
We would stay there again, hands down. Loved it!
