Luis is a really helpful and friendly host, who helped us directly when there was a problem.
From the inside the apartment is really charming, everything you need is there. The view of the beach is so awesome, the sound of the waves, the beautiful landscape.. we already miss it and felt really comfortable!
The beaches in and near Santa Rita are also really nice. For example Santa Cruz, we loved it there. Peniche and Ericeira are also worth a visit. Supermarkets are around there too.
What you should be prepared for is the cold water (bout 18 degrees) and the strong wind the whole time. But on the other hand if you lying at the beach it's really pleasant (you'll need a windbreak).
The only thing we felt not so comfortable with was the missing bathroom door in the apartment. There's a wheeled door between the toilet and kitchen/entrance area, but that's something I'd change :/
