A very small apartment with a fantastic view over the Douro river, however be prepared for all the street music being played down below as well as ongoing bridge work at the moment. We closed the windows during the night and it was nice and peaceful.
There is very little closet space, so you may need to keep clothes in your suitcase depending on how much you bring along and how long you intend to stay.
The apartment is next door to all the port wineries, good restaurants on the Gaia side of Douro and only a short distance across the bridge to the Porto side.
