Wonderful place! The place is private, quiet, peaceful and with amazing views of the valley. A welcome gift was awaiting us on arrival - a homemade bread, cheese, wine and cake. Host is very helpful, responsive and accommodating.
Place is spacious, with nice kitchen, large table, indoor and outdoor seating area, two bathrooms and plenty of bedroom space. It has pretty much everything you may need. You will also find a selection of books on local attractions, art, cuisine, etc.
Surrounding garden is large and lush green with ready to pick oranges, lemons and vegetables.
We visited in the end of November so the only thing we didn't have a chance to try was the pool. It was open, but water was simply too cold to swim.
This location is also very close to Sintra and local beaches (20-30min drive).
Overall, highly recommended! Definitely one of the best AirB&B places we have ever stayed in.
