Our family of three rented a Ooghduyn bungalow for a week. The bungalows are very well designed and using well the space. They are clean and, because they are very new still, in very good shape.
It can in theory accommodate up to 6 people, as the cozy couch in the living room area can turn into a decent bed.
We probably had the hottest week of the last century in Holland (28°C), and therefore couldn't use the beds upstairs in the mezzanine (temperature up to 40° after having the bungalow closed during the day!). On the normal days, it is a good place to sleep though, with a very steep ladder though (which can be blocked using a baby-barrier).
The nights were cool, but started rather late (becomes dark around 22h00). Our child stayed up late every evening, which was okay since it was on holidays.
The bungalow has magnificent windows directed to the beach, giving perfect view on the beach and on the sunsets, which we enjoyed at dinner. Using curtains, you get the necessary privacy when wanted.
Hot water is generated with solar panels, which means you have to be a bit more careful on how long each one showers or doing the dishes (by hand, no dishwasher). On sunny days, it should cover for two time a half-hour of hot water. On other days, one half hour. We behaved conservatively an never ran out of water.
They have a nice Samsung flat panel TV on the wall and a generic DVD player, both with USB sockets (couldn't try them). WLAN is free and good.
The two restaurants left and right of the bungalows (Paal6 and Zee van Tijd) are both quite okay in my eyes, so if you're not up to cooking, they are worth a visit.
The big downside of the bungalows is the long walk between your car and your bungalow. There are 66 of these bungalows, and your walk may be up to 10-15 minutes (approx. 1 Km), which on paper looks like nothing, but when carrying groceries with a beating sun becomes suddenly very, very looong. They do provide a luggage service upon arrival and departure, though, but it's only one bag/suitcase per person. We strongly recommend renting upfront a pull cart (Bollerwagen).
The big upside is of course the beach. You're on it. No need to pack, to go to the beach, no need to install, no need to pick nick. It's there, on your doorstep. According to my 5yr daughter, the sand is perfect. We did some sandcastles, we raised our kite (lots of wind, btw, take a beach tent with you), we fished for shrimps at low tide. Because of the sand banks, your child can walk pretty far out (50m) and still have water below the armpits.
We recommend these bungalows and would like to return.
