The flat was perhaps too rustic for our tastes. If driving it is a very hard drive way to enter. Off of a Sintra main road, huge incline, backing up, manual car, tight drive way. I probably shaved a couple years off of the hosts and my wife back in - I would consider successfully - but my wife does not agree with my rosy memory.
The place is very central, quiet, and accessible to the main square to get the busses for the palace tours, cafes, etc.
The hosts we lovely. Friendly and very informative.
My only feedback was we didn't sleep well in the master bedroom and my wife suffered from allergies. I think mildew as I normally suffer from animals, pollen, and dusts. Overall we had a neutral experience because he host we're amazing. They also made us some delicious scones.
