The views, detailed design touches and hospitality are well worth the climb down/up the hill. I recommend you either park and walk down or simply take Ubers or cabs (we never spent more than 3 euros per ride).
The space is very clean, homey, and relatively affordable considering the incredible views. The host was SO nice and accommodating, waiting some time for us to find parking and still took time out to show us around. We would definitely come back - we have been all over Portugal and this is definitely one of our favorite places now.
