Rui was extremely responsive and helpful in answering my many questions as it was our first trip to Sintra. The apartment was well laid out with thoughtful touches such as USB charging point, brochures & maps that catered to travellers. The heaters worked well and the sound insulation very good. Location is about 15 mins walk to Sintra old town and minutes to the Portela bus station (just in front of the Portela train station) where you can take the new express bus to Porto. We chose not to drive and used Uber to get to Pena Palace etc. If one is driving, there is street parking just outside the apartment.
