We chose De Stokerij because overnight parking in Ostend itself seemed tricky, and it was a very good choice. Oudenburg is a small village in peaceful countryside, halfway between Ostend and Bruges.
Ingrid and Jan are very friendly and helpful, instantly switching betweeen several different languages, and providing useful maps and tourist guides, free wifi, and even use of their laptop.
They are clearly very busy smoking their own ham and salmon, baking bread, and making jam - all of which you can taste at the excellent buffet breakfast. We didn't eat at the restaurant, which is not open every day; a meal there is a set price of €37, which is not mentioned on their website. We arrived on a Monday, which is the day that all the other local restaurants close, but Ingrid directed us to a bar a few minutes drive away which served good snacks.
You do really need a car and/or bicycles if you come here. But if you do, I'm sure you'll have a pleasant stay.
