Thermae Grimbergen Hotel
Many visitors praise the hotel's quiet atmosphere and the excellent, relaxing spa facilities which are often described as large and not overly crowded, offering a good variety of pools and saunas. However, common complaints include dated and basic rooms, poor soundproofing leading to noise disturbances from other rooms and the street, and issues with the quality and value of breakfast. Some guests also found the room prices too high, especially when the spa access was not included.

Hotel with good value for money
Worst experience of my life. I went with my seriously ill brother, and they accused us of smoking in the room, which is false because there was a terrace next door. I had a stomach problem (even though I ate in the restaurant) and I told the cleaning lady because I was embarrassed. On the last day, we wanted to spend it at the spa, but they refused us entry because of their suspicion about the smoking and my stomach problem. The first night, I had to book two basic rooms, and the second night I was able to get the room with the sauna. But I kept the second room for my brother. We were planning to spend the last day at the spa, and they refused us entry because they suspected we had smoked in the room, which is untrue because even the cleaning lady saw us smoking outside. And I don't often have stomach problems, and I'd eaten at a restaurant the day before, so I find it unacceptable that we were allowed to tidy our room and then, just as we were about to go to the spa, were asked to leave. The hotel is awful and doesn't justify the room prices.
The facilities are beautiful and pleasant, and we had a very relaxing and peaceful time. However, we weren't well received by the young woman at reception. The welcome was cold, without any information or explanation. Not ideal for first-timers. The facilities are more numerous and varied in the nudist area... which is a shame for those who prefer to stay in the swimsuit area for the same price. Perhaps a price difference would be possible, or are there other reasons for this?
Always a very pleasant stay at the wellness complex. And every now and then something new is added, always pleasant to discover.
