Great house, incredible value for the fact it could sleep a family of 6. Miguel was a great host, even gave me local cookies! Only thing you should note is that it can be hard to get a taxi/uber from the place as it's a bit out of the way of the center of Sintra, and so lot of cabs don't want to come all the way out there. Took me 45 minutes of hailing one, plus the 15-20 minutes the taxi took to get there. Ended up having to take a later train than I expected. So if you do stay, you should have a car here!.
On the plus side, Miguel offered (though taxi had already come finally) to give me a ride, which was really nice of him!
