We were 6 girls staying for a long weekend in Cascais.
The apartment is very well located to the main area to eat, drink and go the beach. Nuna the host was really flexible with checking us in and gave us all the information about the apartment and the local area.
The apartment configuration is slightly unusual. There are tree bedrooms upstairs. Downstairs there is a small kitchen which leads onto a larger kitchen and area to eat. On from the kitchen is another bedroom with bunk beds, we didn't use this room and it was be fine for kids I guess - but it wasn't very light or inviting. There is a lounge area and patio which we didn't really use.
The apartment was a convenient, spacious base for us.
