Sintra is justifiably a tourist town; there is a lot to see and enjoy. But Casa Azul is a true bargain in a town where there aren't many. Antonio was a warm and welcoming host and the atmosphere is relaxed and most pleasant. Facilities are at least equal to other hostels and the location is convenient to the train station and buses which form the tourist hub. Highly recommended, particularly for a multi-day stay in Sintra.
