We enjoyed our stay in Sintra with Maria! The apartment was immaculately clean and walking distance to the main tourist activities in Sintra. Her partner at the local hostel greeted us and was helpful in carrying our bags up to the apartment, giving us a lay of the land, and letting us know to contact him with any questions.
The biggest challenge was parking! Unfortunately we visited on a Tuesday when the local market takes place, and after looking for parking for over an hour, we decided to park in the paid public lot just outside of town. If you’re driving, be aware that parking in Sintra can be very challenging. Once the market ended we were able to take a taxi back to our car and park it within walking distance of the apartment.
