Mateus's apartment is wonderful. When we arrived our host Rebecca was there to meet us. She was super nice, knowledgeable and a great resource to answer any questions and assist with transportation needs and arrangements.
The apartment was clean spacious and in an ideal location. Across the street was a supermarket and padaria (bakery).
The walk to the center is approximately 20 minutes. Walking along the promenade is a scenic view of the Atlantic Ocean.
Also if you did not want to walk into town a couple of blocks away is a bike rental shop. There are also restaurants and shops within a five minute walk.
It is without hesitation that I recommend Mateus's apartment for your stay in Cascais.
