Though we did not meet Maria Joao in person, she was such a helpful and accommodating host all along; always approachable. She even recommended good restaurants and sightseeing spots to us. We were warmly welcomed by her amazing friend who let us in the apartment.
The location was absolutely clean, spacious and comfy. The perfect place to stay if you are planing a trip to Cascais.
Highly recommended!

PS: Thx for the Sushi restaurant recommendation :-)
