Had an amazing day with my mom there but it is hard to walk up there we took the tuk tuk cab up and the buss down it was very beautiful and the palace rooms had lovely detailing but in my opinion its the outdoor area of the palace and the terraces around it that are the hit factor. Inside the palace there is around 10-15 rooms and around 4 bigger halls it is very nice and again a lot of amazing wood craved details and marble and staying glas as far as you can look but its not your typical type of palace with lots of gold and kitsch and pompous rather it is arty and detailed with love and devotion. If you are not really in to that go up buy the ticket for the garden but not for the palace inside you will have amazing views and get off a bit cheeper it is an expensive experience for 2x people we payed following: 25€ for the cab up, 2x 14€ for the palace garden admission, 2x 14€ for the palace inside area admission, 2x 7 € for the bus to come back down come to overall 95€ for 2 people to see one palace on top of the fact we where on holiday in Lisbon so we had to buy train tickets to get to sintra in the first place. Also there is a shop there that sells snacks and drinks and the items they do have are reassnobly priced especially compared to the tickets and the fact they are quality products but variety is very very very limited. Staff is friendly and accommodating.
