The B&B Berlaymont was exactly as described and Madeleine was a great host! Polite, helpful, accommodating and always with a smile in the mornings, with a great breakfast.
I needed a quiet place to study for a few days and the Madeleine's place was the perfect place, calm, well situated to where I need to go and to public transportation and the room was exactly as in the pictures.
I would not hesitate to go back to it and recommend it to anyone who needs to be around the EU institutions but doesn't want the usual middle-of-the-road hotel experience at very expensive prices.
