It was pretty conveniently location just inside sintra, very short walk from the station. Check in is all online and they ask for a good amount of information, no one that works there there - it was clean though, and quiet so I didn’t mind (mine worked just fine) and they were very, almost overly communicative - very thankful to have a place to leave my bags while I went through the city even after checkout but would have liked some kind of security for the bags, though no incident
