We stayed at Maria and Joao's apartment for five nights. Overall the stay was very enjoyable and the location very central - everything is within walking distance. The apartment is in an old period building and retains a lot of its original charachter and charm.
On the first night there was a very noisy party in the apartment directly above that went on into the small hours of the early morning. Out host Maria responded and was very apologetic, though was unable to do much as the apartment above was not theirs; they did say they would speak to the owner. Thankfully the remaining four nights were quiet.
There are many restaurants, cafes and bars to choose from all within walking distance; as well many museums and other attractions to see. The living room opens onto an external balcony, which was really nice to have during the day and evenings and just enjoy this small street.
Overall we enjoyed it and would recommend.
