Yes, it sounds cool to stay on the Waterloo Battlefield, but it's really not. You are in the middle of actively farmed fields. The Belgians did not really preserve the battlefield at all, so you are just out in the middle of nowhere and stuck. If you don't drive, you are double stuck.
The rooms are busted up and extremely tired. The restaurant in the hotel is quaint in that oh this is a completely amateur affair but the people are nice kind of way. The breakfast is an absolute robbery, but there are zero other choices. Just stay in Brussels and head out in the morning and your life will be much better.
