In short: everything I needed for my surfing trip to Ericeira, which came with more nice additions.
The longer version: The place lies at a very nice spot which overlooks a small hill going down directly to the sea. During sunsets and when it is sunny in general, it is a very beautiful place to chill at the accommodation pool or balcony (if that room is rented). Sharing the house with just some other guests makes this place a nice and calm environment especially for the people who either travel alone or in pairs. The hosts are very accommodating and helpful, providing a nice breakfast each morning. The room and bathroom were very clean on arrival, and the place itself gets a cleaning regularly, keeping it tidy for all the guests. During the stay, the hosts provided new towels and would arrange other stuff on request if necessary.
The place is a 15-20 minute walk to Foz do Lizandro, which is a nice big beach with some terraces which provide breakfast, lunch, and dinner. There is also a surf school and rental which provide lessons right at the beach itself. The center of Ericeira is a 20-30 minute walk along the road which overlooks the sea and passes by another beach (Praia do Sul). Ericeira itself contains a certain amount of terraces, shops, restaurants, and a few supermarkets.
All in all, a very nice stay with kind hosts. Would definitely come back if I would go on the same trip.
