Hotel recommendations in Cascais Portugal

My wife, 8 month old and I are thinking of staying in Cascais Portugal for part of our trip we are going to be in Lisbon (3 days) -> Porto (4) -> Then end in Cascais for about 2-3 days. We figured it would be a relaxing end since we fly out of LIS and this is by the beach does anyone have any good hotel recommendations for staying in Cascais during the summer mouths?
