I've stayed at the Bastion in Bussum several times because it's near the Dutch office of my employers. Flying in from the UK it's very easy to get to - catch a train from Schiphol to Bussum Zuid (usually direct but you might need to change at Weesp) which takes about 30 minutes, and on arrival at Bussum just walk across the carpark. The hotel is absolutely right next to the station.
The facilities are clean and minimalist. Beds are comfortable (to me, anyway) - I normally stay in a twin room (2 single beds). The bathroom in one of the ones I stayed in smelled a little musty - it's a "wet room" arrangement, the shower has no cubicle or tray, just a curtain around one corner of the bathroom. The shower itself tends to be very powerful - a strong spray of water at any temperature you like, which at full power actually stings the skin with its force.
Although the hotel is next to the train station, the rooms are very quiet and you don't actually hear the trains. Each room has the basics but nothing particularly fancy. There's a "restaurant" (really just an area off the foyer with a dozen tables) and a bar which is an extension of the front desk. Food is obviously pre-prepared (with the exception of fresh veg) and basic but decent quality and tasty. There's a selection of stuff on a buffet for breakfast, from bacon and scrambled eggs, cereals, fruit, through toast (pick your bread and put it through the toaster yourself!) with a variety of preserves, to various meats and cheeses. Take your pick.
There are rarely more than a couple of members of staff in evidence, but they're helpful and friendly and make visitors feel very welcome. It's not a destination hotel but it is a very pleasant place to stay.
