Kuros' place is a great apartment for a stay in Brussels. Firstly the location - the apartment is near the US embassy just off the R20. This is a big road, but it was silent in the house and you are a very short walk (five mins max) from Arts-Loi and Trone metro stations. Better than that it's at most a 15min walk to Gare Central, and that's a great walk through the Parc de Bruxelles.
Check in was very easy - Kuros was kind enough to allow us to drop bags off early. We were met by the person cleaning the flat who handed over the keys. There were snacks and a bottle of wine waiting for us, which was nice. There are no instructions in the house, but Kuros was very prompt in responding and recommended a good area for eating out, and we didn't have anything that really needed explaining in the house.
The apartment has a large, good living room which includes a good dining table and a balcony adjoins the room. A hallway runs from the entranceway that takes you past a kitchen (good size, all usual amenities including dishwasher), a toilet, the room with a bunk bed (which as another reviewer has pointed out would be enhanced by having a blind or curtain), then the bathroom (with shower attachment) and the main bedroom, which is big and was a very comfortable room. I'm not in general a fan of two-single-beds as a double bed, but both nights were really comfortable for us so it was no problem at all.
I really recommend the place - it was a great base for a long weekend. Thanks Kuros!
