Cascais is a fabulous location to explore Lisbon (easy/cheap access by train to the city center) and surrounding area (Atlantic beaches, National Palace of Pena, etc.) and Cascais itself has a great seafront/beaches and wonderful winding back streets with a bunch of great restaurants.
The apartment is nicely outside the hubub of Cascais tourism, but just 10 minutes walk down to the main areas and restaurants.
It's nice, clean, and simple, perfect for vacationers. Joa is a great and helpful host, with very quick answers to any questions.
We'd be very glad to return!!!
