The Hotel looks nice, but unfotunately they dont have space to handle their guests. 15-20 min waiting time if you wants breakfast. Or as they said why dont you just eat breakfast later today, or you can pay extra and get room service. Especially amased by the offer to pay fully again for breakfast in the room. Or even better if you skip breakfast we will give you a late check out!! But you have paid for the breakfast so we will keep the payment.
I have worked in 13 different countries, travelling quite frequently, and have never experienced something like this. The Hotel itself is nice, but if you care about your morning coffee or breakfast before your meetings in Brussels, find a better hotel
