We chose this AirBnB because it's in a slightly flatter location compared to a lot of the inner streets plus only one flight of stairs which really helped with mobility for my grandmother. It is on the other side of the river but at no point did we feel we weren't able to experience Porto in it's entirety. It's next to the beautiful monastery and has a lovely green space out front as well with some of the best views of Porto.
The AirBnB itself was super clean and had absolutely gorgeous views, check-in was very hospitable and Paulo helped me find parking as well. Plus he had great suggestions for things to do and where to eat. I would definitely come back and stay here!
