Great host and house. Isabel went out of her way to make sure I got the key at my arrival time even though she wasn't going to be at home. The room was comfortable and the house has a guest accessible kitchen and terrace with a view down the valley of Sintra Palace.
I like to walk and was able to visit all the local tourist areas on foot, although the area is a bit steep so be prepared. There are a couple great cafes in the village of Sāo Pedro that aren't as full of (other) tourists as the ones in Sintra village are, if you're looking for a more authentic experience in Portugal. Isabel made some great eating recommendations in the village too.
