I stayed with Matilde for 4 days and it was really nice. Matilde is very friendly and we had some interesting conversations. She also gave me helpful advices which places I can visit. Her flat is clean and comfortable and not far away from the train station. I walked from her flat to some of the very beautiful palaces and magical parks in Sintra (Moorish castle, Palace and park of Pena, Palace and park of Monserrate, Palace and park of Regaleira, Palace of Sintra).
I can really recommend a stay in Sintra and Matilde's flat!
