I couldn't recommend Paulo's home enough, this place is the perfect spot for a stay in Sintra. The village of Penedo is lovely and quiet, succulent market on week-ends , you are about a 10 min drive to the best beaches of the country and also minutes to the popular attractions of the area.
The House of Paula and Ferdandina is very lovely and relaxing, and the garden is stunning!
Going down to the lemon trees in the morning was an absolute delight.
Last but certainly not least Paulo and Ferdandina are extremely helpful and without a doubt one of the most wonderful people I have ever met!
