We were two families of 4 and we stayed at Paula's place for 7 nights. The bunk bedroom was ideal for the 4 children and the two other rooms were ideal for the two sets of parents. Even though we only had access to 3 of the 4 bathrooms, it was still perfectly sufficient for the 8 of us. The kids used the pool almost every day, even after playing on the beach. The 9-person van we rented fit nicely in front of the allocated garage space. (Note: Residents of the large complex park along the curbside, which could make it difficult to park in the allocated space or to pull out of the driveway onto the side-street.)
Paula left us a basket of fruit and a bottle of wine on arrival, and communication was easy. The kitchen was supplied with appropriate kitchen tools/items so that we were able to cook a meal after a long day at the beach or exploring. The only downside to the location of this condo was that there are no restaurants close. As a result, we searched online for restaurants on at least three nights, either walking 40+ minutes down to the center of Cascais, 20+ minutes straight to the water off the main road, or 10+ minutes to Bicuda. If our party only consisted of adults, it probably wouldn't be too terrible, but we had 4 children between 8 and 11 years old, so they 'willingly' plugged along.
