Great place. It is really a little bit small but nice and clean and definitely good for the price. The stairs are a little bit difficult to 'climb' (especially with heavy luggage) but that is what you pay for a cheaper, clean, apartment in a very well located apartment in Brussels. The hotel Agora employees a are really nice and friendly. It is a really helpful that they keep your luggage if you get there earlier than check-in time.
We were there during the he hottest summer in Europe and this attic place was a little bit hot but I think thesituation was unprecedented and unusual for Brussels.
