The apartment is about a 20 mn walk from the center of town and very close to the Portela train station. Filipe was very helpful in giving me tips on things to see and bus schedules. He even walked with me since he needed to go to town and showed me where everything was. There are so many beautiful things to do and see in Sintra, one and a half days cut it a little close for me. Bear in mind that you cannot leave your bags on the day of check out so plan accordingly if you do not have a car to store them, or stay an extra night to make sure you can see as much as possible.
