We spent a wonderful week in Katerina's apartment, the location was amazing, just across the road from the train station and trains to Cascais, Estroil and Carcavelos beach within minutes. The apartment was spotless, well stocked and plenty of clean towels and sheets, a lovely view of the ocean. The supermarket is 5 mins walk and 5 mins walk to the beach. We didn't make it to Sintra but it will be an excuse to come back. Highly recommend Katerina's place.
