We thoroughly enjoyed our stay and the location was perfect. Clear and easy-to-follow instructions to access the flat, and the internet was great (I had to work). The kitchen is basic and did not really entice us to cook our own meals (there is a great wine store around the corner and we found a great selection of cheeses, though). There are lots of great restaurants and breakfast places in the neighbourhood.
The only issue was a party elsewhere in the building on the Saturday evening. We could hear the music as we entered the building and the bass reverberated through the walls and floor. Sadly, we weren't invited to the party but heard them having fun without us ;)
When next in Brussels, I would definitely try to stay here again. It is super convenient and good value for money!!
