The location of this flat is excellent, but beware if you're a light sleeper. It can be quite noisy in the evenings. (If you like to be out late at the local bars though - this is a good option!) Host is quick with communication and responsive.
I was personally disappointed with the condition of the apartment. The stairs were dirty and smelled. There was peeling paint in the bedroom and the water closet ceiling was unfinished. The experience was not what I have come to expect for the price. If the owners give the place an update though, the flat has loads of potential. The central location is ideal for seeing Brussels.
