We had a very pleasant stay in Maria's house. She, her husband and daughter were very welcoming and helpful during our whole stay.
The house is close to the train station (16 minutes to Cais do Sodré) which is very convenient to visit Lisbon and close to Cascais (by train), Sintra or Guincho beach (by car) which offers the possibility to alternate city and countryside/sea. The house was roomy enough for the 2 families who were travelling together (4 adults and 4 children).
We spent a week in April and couldn't take full advantage of the garden but it is not overlooked and promises to be very enjoyable in warmer times.
