Teresa met me and provided some helpful information. It was nice to find some basic essentials provided - tea and coffee and some fruit, not needed as I had taken my own.The accommodation couldn't have been located more centrally - a five minute walk up the hill and you arrive at the historic centre - right next to the National Palace. The Tourist office is at the right as you reach the top. It was perfectly situated for sight seeing.
Luis very kindly picked me up at 0645 to take me to Sintra station as I was headed for the airport.
I felt perfectly safe as a female even walking around late at night.
Some visitors may find the poor signal in the accommodation a drawback which was mentioned to me but could be an issue if you need to catch up with work.
