Our stay in Cascais was wonderful. This space worked perfectly for me and a friend traveling to Portugal for the first time. The location is a bit of a walk to the downtown area but the oceanside walking/biking path was gorgeous and a straight shot to great beaches and shops in town as well as unique buildings and sights. We also went to 2 restaurants along the water, headed away from downtown which were only about a 5-6 minute walk (we found this spot just by walking down the ocean walk away from town, so turning right on the main ocean road.)
Overall, the space is great! There is a small grocery and a great bakery right around the corner from the apartment. Our hosts were attentive, helpful, and provided a great experience for our first visit to Cascais - we would definitely recommend and we look forward to coming back in the future!
