We had a great stay in Ingrid's and Martin's guesthouse. It was a very uncomplicated and friendly communication with them. The guesthouse has all, you need. Also we could use the garden, where you have a nice view.
We stayed there with a baby, it was really nice, that Martin put some baby stuff in the guesthouse.
The train station is near the house, so it's perfect to stay there, if you plan to visit Lissabon and the beach.
