Exceeded expectations greatly, highly recommended!
While the photos are accurate, the seaview is even more spectacular in reality. The whole top floor faces the ocean, as do the main balcony and another on at the roof of the house. The place really started to feel like home by the end of our stay. Hopefully we'll be able to return some time.
Luis' place is located in a really nice condominium – feels very safe. Parking was no issue and we could walk our dog right outside the place. The houses in the condominium are well-designed in that you are never facing the neighbours and can enjoy total privacy. Luis' place too, despite the fact that it's quite big and has lots of outside area.
The house 5-15 minutes walking distance of everything: the beaches, old town, supermarket, town center etc. I recommend Ericeira in general because while small, it has everything you might need even over a longer stay (not true for all small Portuguese towns, in my opinion).
Moreover, Lisbon is 30-40 minutes away, so you can easily get to the center of the action, if you wish.
Luis and Isabel were perfect hosts: the couple of times we had questions or requests, they responded within minutes and solved whatever question we had. We stayed for 2 full months and had no notable issues, just me asking for more information mostly.
Muito obrigado e até a próxima!
