As the host will note before you book, there is a worksite next door. It was not too bad for me as it was generally during the day when I was out exploring, but if you are looking for somewhere to rest in the afternoon before dinner, this may not suit your needs. Once the construction is done, this would be the perfect place to stay.
The location is awesome, so many cute cafes and bars around the streets, easy walking distance to all the sites and not too far from Sao Bento Station (if coming in to Porto from the train).
I really appreciated all the tips and extra effort to give some detail on the local area.
