We really enjoyed our brief stay in Sintra. Our host accommodated us with having lockers to store our luggage while we went sightseeing as we arrived in Sintra in the morning and our check in was not until 3:00pm.
Location of the property is very central, close to the train station so you can either walk or you can Uber it. We never met any hosts but they were quick to reply back by phone messaging. I would definitely recommend the casa Estefania for anyone wanting to visit Sintra.
