I had a large room with a good size double bed in it. The room was at the end of a corridor separated by curtains from the rest of the apartment. The corridor had a separate bathroom and toilet. The room itself had no lock but the apartment required two keys to access: one from the street and another interior door.
The apartment is very close to ULB (Universite Libre de Bruxelles) Solbosche Campus: where I was attending a conference. It was maybe 5 minutes walk with plenty of local restaurants.
I was given a couple of hand towels plus a bath towel and soap. Also, a bottle of water, jar of nuts, and a mandarin. The wifi was fast and the password was visible on the wall.
Bernadette and her partner were very friendly. They were both french speakers with enough english (combined with my small amount of french) that we had no problem communicating.
