We had a lovely stay in Maria Saudade Apartment for 2 nights while exploring Sintra. It is perfectly located in the heart of the old town, walking distance to the Sintra National Palace and restaurants. Quinta da Regaleira and Castle of the Moors are also nearby if you don’t mind a decent walk on an uneven path, we love it! The apartment is small but fully equipped with all you need and is great value for money. Highly recommend.
