I stayed in the house in total about four months and it was a great experience.
The house is big with several rooms rented out, the kitchen is fully equipped, the lounge is spacious and it is nice to sit outside on the veranda.
The station for the Lisbon-Cascais train is a few minutes away. You can walk to the beach approximately 15-25 minutes depending which beach you choose. Supermarkets and a self-service launderette are about 10 minutes away and nearby is a pub if you prefer a drink in the evening.
Overall a good experience and I will not hesitate to book again if I need accommodation in the area.
