Small, functional room in Anderlecht, a workaday, slightly scruffy district of Brussels.
Location: handy for the Zuid/Midi train/bus/metro station (which has connections to the airports), about 10 minutes' walk away. Not so great for the city centre itself: area is reasonably well-served by public transport links, you can get from the flat to the centre of the city in 20-30 minutes or so.
Area has numerous cheap cafes, bars and middle-eastern eateries. Well-stocked, cheap food/fruit-shop is a minute away from the front door. I especially recommend Cicek Kebab, nearby on a corner of Rue Bara. Stand on a stool and look out of the small window and you are peering into the courtyard of the old vet school, a huge and impressive 19th-century complex currently being renovated.
The flat: this is an airbnb which is clearly not inhabited apart from by airbnb clients! I only saw Flavio on arrival -- communications were easy and prompt, no problems there. He helped me with my luggage -- it's on the 3rd floor, up numerous flights of stairs, in a 19th-century building that's in a slightly run-down condition, with the entrance area especially in need of refurbishment.
The room itself was clean and acceptable for the price. Tall visitors should be aware that it's a garret flat right under the eaves of the building -- I'm 185cm (6'0.5") and knocked my head on the sloping ceiling once! Single bed with clean sheets and one medium-sized towel; TV; microwave; small rudimentary plastic kettle (socket near the kettle/microwave didn't work so I had to use another one on the other side of the room). A plus: wardrobe with 12 proper wooden hangers! Wall-mounted heater worked OK.
"Bathroom" and toilet are located in separate tiny rooms off the landing (and are shared with two other bedrooms; I heard but never saw the occupants.) Shower-room is of bare-minimum size and is a little tricky to manoeuvre within for any regular-sized human. The water itself, however, is hot and plentiful (shower force strong) despite being up on the 3rd floor. Toilet (with washbasin) similarly "Lilliputian" -- could be a tight squeeze for overweight folk or those with long legs.
In summary: basic, no-frills airbnb accommodation at a reasonable price. Worth considering if you are visiting Brussels but don't need to be in the centre of the city and don't need fancy surroundings.
