Rui is a great host, replying quickly and giving us some fantastic tips. A tip to future travellers to Rui's- you don't need a car. We got a £35 Uber from Lisbon airport to Ericeira and then walked to the beaches each day. A 25 minute walk or so. And if you don't feel like walking, there is a beach bus that runs every hour all the way up the coast for a Euro each.
