The appartement is exactly as pictured. It is comfortable and clean. The location is excellent, both for work and for tourism. It is a short walk to the European institutions and a mere ston'es throw from the Etangs d'Ixelles and the Abbaye de la Cambre - a beautiful historic area of Brussels.
Other reviewers mentioned that the rooms on the lower floor are a bit gloomy but personally I prefer a dark bedroom as I cannot sleep if it is light, and I wasn't planning on spending much time in the kitchen anyway.
As it is an old building, there isn't much by way of soundproofing between appartments but I say this as a heads up - it's nothing that ear plugs won't solve. I always carry mine and I had no problems.
