We had an excellent stay at Matilde and António's house. The space is so light and open - perfect for eating in and relaxing at home after a long day at the beach.
The hosts were always available to answer any questions we had, and even put a little slide in the garden for our children to play on.
The location is super - walking distance from the beaches and all the good restaurants. I'd highly recommend visiting Cascais and staying at Chalet Arminda.
