I regarded this as a 'find' since prices in March in Brussels can be a bit nuts. But initially 'finding' it was hard starting from the EU district with some bus routes redirected. It is best treated as being near Avnue Louise and getting off a tram at the Vleurgat stop. On the way to the hotel (a couple of blocks, some maps make it look like more) you will pass an Antalia kebab place that is really good!
My room faced a small park at the back and was quiet, the breakfast was fine, on a par with other 'standard' breakfasts (and the standard is high in Brussels). So, quite happy with knowing about this hotel for the next time I am stuck, although when prices are lower I would (and did) likely stay in a better location for EU district. This would not be too bad a location for going downtown but the trams did not seem really frequent at night.

I stayed one night at the Hotel Capital on a leisure break. It is quite new and does seem to cater for business travellers as stated on the Hotel information. The Hotel is a mile or so from the centre of Brussels and too far to walk back to at night. The rooms are quite modern in style but are beginning to look a little faded. I had a room at the back and the aspect was excellent, looking over a most attractive garden. The breakfast room has the same outlook, with huge glass windows and made a positive start to the day. The breakfast was continental and was adequate rather than comprehensive. Staff were helpful and pleasant. I needed a plug for my bath and received assistance at once to find one, although I had to go to another room to find one myself, because the receptionist could not leave the reception! I would have no hesitation about staying at the Hotel based on service and quality, but for me, it was a little off the beaten track.
