João is more than just an apartment owner. He is well known (as a surfer) in Portugal and can direct you to the right places and beaches in Ericeira and around.
João will do anything to make things comfortable. For us with a 1 year old the apartment with the pool in front was amazing.
To go to the centre the landscape can make it feel like a hike, but it only takes 10 minutes. A car will be very helpful to get to other beaches which are worth a visit.
Our two weeks in Ericeira were really nice, we definitely will come back!
