We loved staying in this apartment! It was very clean, in the heart of the old part of Porto . Although it is in an area that gets a lot of visitors (next to the cathedral) the location is quiet as it is not on a street with cars. The apartment is small, with a compact kitchen and a bed that folds down, but it is very comfortable and has the feel of an art museum. The owners (3 of them, I think) were very attentive and available. We would definitely stay there again.
