Beautiful stay in Sintra. Filipe and Vera are very kind, they'll give you the best advices and will do their best if you arrive earlier or must leave later. The house is very clean as shown on photos and the breakfast is good with Filipe grandma jam. The location is also very good. It's better to stay there than in the historical center of Sintra because it's convenient for the luggage as the train station is just near and the departure of tourist bus is also near so you can avoid the queue to get on the bus.
Would definitely recommend these hosts.
