Leonardo and Carol are outstanding hosts. Even though small, the place is fully equipped for extended stays and the kitchen in amazingly complete (I always like to cook at home so that's something I really notice, haha ). There is a very charming balcony too. Couldn't recommend more.
I just missed more things to do around (walking distance), like cafes and restaurants, but that's definitely not a deal breaker, since Cascais is and excellent neighbourhood.
Go ahead!
