We stayed at Villa de Velduil with 6 people and found the house catered well for that amount of people. Beds and furniture were comfortable, kitchen very well equipped. It was, furthermore, lovely to have such a big garden/piece of land around the house and consequently lots of privacy.
Apart from that, the village of The Cocksdorp is at walking distance and has a good supermarket and several restaurants on offer, while heading in the opposite direction means a walk straight onto the beach (approx 20). It's a quiet corner of the island but with all ameneties nearby and good connections to the rest of the island as well.
In conclusion, it's not cheap, but you get a lot for your money.
