The apartment is much more than “cosy”. It is spacious, comfortable and very well set up.
The living area is large enough to make the apartment perfectly suitable for anyone planning an extended stay. The dining area comfortably fits a table for six and leaves a spacious sitting area. The kitchen (which, as we were there only for two nights, we didn’t use) was a real kitchen and well set-up.
The bedroom was also a generous size with plenty of wardrobe space.
You could hardly choose a better location. We managed luggage in an easy walk from the central station and then walked everywhere for all our city sightseeing. The area is lively but we had no problem with noise.
I’m sure you can find cheaper but I doubt you can find better in Brussels.
