We stayed in the Aloft Hotel in November. It's a modern and innovative hotel and is great for travellers on a budget.
Situated around a 2 minute walk from one of the main suburban metro stops it's easy to get in and out of the centre of Brussels - only 1 or 2 stops to Brussels Centraal station all of the big tourist attractions. Being out of the centre means that there is a significant price difference, but this hotel is not too far out to be an annoyance.
The room we had was spacious and comfortable. It was very well designed to be as economically friendly as possible and to make the most of the space they had to work with. The bed's headboard acted as a separating wall from the bathroom, for example, and the shower and toilet were concealed behind a huge wall-mirror door.
All was clean and well-maintained (though we didn't have a working hairdryer, but I'm sure if we had asked for a new one it would have been supplied).
The staff were extremely friendly and helpful. Check-in was easy and when we mentioned that we had forgotten to bring a European plug adapter with us they were able to lend us one.
The only downside to this hotel is that the rooms did feel a little cold and impersonal, and at the time of year that we went the place was largely empty so we did not want to go and sit in the bar or cafe by ourselves!
Nevertheless, would recommend this hotel to anyone travelling to Brussels.
