I can not recommend this house and the host, Maria Ana, enough. For the house, we had a group of 12 and there was more than enough room for everyone. The pool and patio is amazing and a perfect place to hangout.
Maria Ana (and her niece Carlotta) were equally wonderful. Maria Ana picked us up from the train station and then had a delicious food and beverage spread waiting for us on the balcony. They were also extremely helpful during the stay with any questions we had.
If you have a big group, this is the perfect place to stay, and it is an easy 10 minute walk to downtown Cascais.
