We had a great time at Marias house. The house was perfectly suited for us (three kids and four adults), there was plenty of space and the garden was great for the kids and the terrce with barbeque for the grown-ups. Everything we needed was there. Maria was very welcoming and uncomplicated. She had very good recommendations for restaurants and activites. Sao Pedro is a bit outside of Lisboa, but there is a cummuting train that needs only 30. We had no car but absolutely no troubles getting around. The beach and the lovely town of Cascais are nearby and a trip to Sintra (highly recommended) is easily possible. We would return any time.
