Great place, in a quiet location off the main road, surrounded by nature. Loved the view from the living room.
Location is close enough to Sintra old town, though I wouldn't necessarily consider it walking distance (unless you're in great shape and climb hills fast or have about an hour to spare each way). Uber however services the area and is very affordable.
Fridge was well stocked. The host also gave us a bottle of wine and breakfast on the first day., and went above and beyond to help us book rapid tests for our departure. Thanks Jorge!
