Martha is a very helpful and communicative host who gave us a lot of help finding the place.
The apartment is spacious and well appointed. With nice touches such as an honesty bar with a good selection of port and welcome decanter of port.
The apartment is a good walk from the centre of town. But a bit far to walk to the Ribeira and the old part of town. Using Uber was cheap and efficient way to access that part of town and the Gaia area.
