Great flat for 3 adults! Miguel's flat was the perfect location for our 2 night stay in Sintra. Located right next to the city center and a 15 minute walk from the train, we couldn't have asked for a better location. All of the major Sintra attractions are right within walking distance and the tourism/visitors center is less than 5 minutes from the flat.
Miguel was very accommodating and allowed us to drop our bags off early. He checked in to make sure we did not have questions or needed information about Sintra. The flat also had snacks and coffee for a fee to use if we needed. We took advantage of the coffee.
The only negative we ran into was late at night, the flat above ours could be a little loud and the bathroom was only semi private as it had no door.
