We were on Maria house in March with family od four and we are more than satisfied.
Three is lot of space, nice garden and place for a car.
House is located above the old town, 10min walk from beach. Grocery shops and supermarkets are very close.
Ericeira city is definetely worth visit. There is always where to go in the city also it's is very convinient place for trips into most turistic places.
