Great place right in the Sintra old town. Very kind hosts, being flexible with check-in/out times, very helpful and welcoming. Apartment well equipped, clean and efficiently furnished, with personnalized artistic touch. Little noisy during the day and evening (restaurants, shops and street music on week-ends right below the windows), although becoming very quiet between 11pm-9am (out of the tourists crowd). Parking = an issue during the day, much easier after 6pm (~ 5 min. walking radius).
Sintra and surrounding is a kind of a fairy tail, worth spending at least 2 full days!
