We loved our stay in Ericeira with Diego & cousins. Tgey were great hosts! The apartment was really great, clean, well designed and big enough for the three of us (with baby) and we liked the location in a pretty quiet residential area. One beach is pretty close and also the maintown is not to far. We were renting a car and did go and see the surrounding cities like Sintra, Lisbon, Mafra etc, so everything nearby.
