We liked everything about this B & B - we did have some problems with the locks (you get a set of keys that operate gate, door, etc.) but we're not used to dealing with multiple locks and old style keys.
Lovely, well-run B & B located quite convenient to center of Sintra,near National Palace and shopping area (just a short downhill walk). There was even a bus stop almost directly in front of the property. The guest house is decorated beautifully, has a pretty garden, and gorgeous views from its terrace. Hosts are particularly helpful and gracious. It was a pleasure talking with them. This was one of our favorite stays when we traveled recently in Portugal.
