The B&B is located 1 min from the subway (2 stops from the train central station), and 5-10 mins walk to the Grand Place. The entrance and the 3 rooms face a small narrow road (almost an alley), adjoining roads with restaurants and pubs.
Breakfast is served in the common ground floor room and is a collection of cheese, jams, croissants/breads, coffee/cappuccino/tea, yoghurt, fruits, cookies and cereals (some items and water are always available to the guests). No eggs and bacon or other hot meals are offered.
The owner is very nice and speaks English.
The room on the 3rd floor we were in was in mint condition, extremely clean and roomy: coffee machine, flat TV with accessible HDMI, (loud) A/C, speedy Wifi (30-40Mbps UL/DL), big shower, welcome pralines and complimentary water in a fridge, window facing the roofs with plenty of natural light were available.
IMPORTANT: The stairs to the rooms are *extremely* steep and narrow, with everything that implies (especially safety-wise)...
Bringing upstairs anything bigger than a cabin trolley will be very difficult.
The windows on the staircase cannot be opened. No fire extinguishers/sprinklers are available in the room/common room/staircase. This seems to be common in Brussels (as we saw in restaurants), although everything is wood...
The very loud AC meant we had to keep it off and the window open instead: you will hear the noises of the below streets teeming people in pubs and restaurants until very late (2-3 am).
