This apartment is absolutely perfect. It's in a lovely location, really pretty, and great as a base for walking up to the castle and palace and also around town. The apartment is very nice inside and has a nice terrace with views (though sadly we couldn't use it as it was rainy!). Definitely stay here - had everything you need and was comfy. I would recommend not travelling by car to sintra as the traffic gets clogged up, and the train from Lisbon is very easy and very cheap! It's a lovely lovely place.
