I stayed at the hotel with a couple of friends at the end of April. It was exceptionally hot, but despite promises of air conditioning on the web site, there was none. We arrived in the afternoon, got our keys and discovered that the beds in the rooms were not made. It took about an hour of running back and forth and many phone calls to the front desk, to fix the problem. The front desk people were far from obliging:they kept answering phone calls and did not apologize for keeping us standing and waiting for a long time. The front rooms face a busy road, so it was impossible to keep the windows open, despite the suffocating heat. We could not get help with the luggage and had to carry it through a gravel covered parking lot. To top the inconvenience - there were no bed side lamps. Like so many hotels, the rooms were poorly lit and the lack of lamps at the bedside, prevented any effort of reading in bed.
The only positive aspect of our stay was the convenient location, in the town's outskirts (plenty of parking space), within walking distance of the Het Loo grounds and easy to navigate to the nature reserve nearby.
The place claims to be a 4 star hotel, but needs to make some changes to deserve such rating. I would never stay again in that place. I expected more from a Best Western hotel.
