My family of four (two toddlers and my wife) relocated to Cascais and we chose Mariana's Airbnb because of space, location and convenience as our hub while we settled for a more permanent accommodation.
The airbnb is set-up for families or a larger group with toys, a crib and the conveniences for a home-away-from home. The kitchen is fully stocked and there is enough closet space as well.
Across the street there is Auchan (like a Target) which has everything one needs. A few blocks further is the tourist center and beach which makes it convenient for sightseeing or hop on a train and visit Lisbon.
Excellent location and Mariana was a very accommodating and responsive host.
