This apartment was lovely. The skylight and the windows let in a ton of natural light. As others have mentioned, yes you can hear seagulls. We loved this! There is a lovely view from both the front and back of the apartment.
Our host greeted us in person and gave us plenty of tips in exploring the area. They communicated quickly via WhatsApp and when we needed a few more towels they dropped them off for us quickly.
We would certainly stay here again if (when?!) we visit Porto in the future.
