I would highly recommend staying at this stunning Airbnb.
Amazing house for a stay in Cascais, especially with children. We stayed with our two-year-old, who adored being able to play in the living room while we relaxed on spacious balcony.
It’s incredibly close to the seaside, restaurants and a beautiful nearby play park.
There are plenty of amenities for cooking as well, and several spaces for eating indoors or outdoors.
The only recommendation I would have for anyone bringing small children, is to come with a stairs gate, as there are many wooden stairs.
