It's a nice, new and modern hotel, located in a nice, central area, next to the european buildings and the Schuman metro station, from where you can reach Central Station in 5 min. 2 markets are also near the hotel. The rooms are spacious, with a modern business design, although a little to dark in my opinion. The staff is all young (students i think) and very nice. A little unusual, but most welcome thing, which we didn't find in any other hotel before:you can decline the daily cleaning in exchange for 5 euros/day, which you can use for example for the breakfast. Also, for the breakfast they have an unusual way of setting the prices: 3 items for 6 euros or 5 items for 10 euros. One item can be for ex a coffee/tea or ham+cheese+bred or a croissant+butter+marmelade, so with 6 euros you can eat quite a rich breakfast.

The rooms are very chic and trendy..the TV even has a USB port!
Apart from that here's why we loved it
cosy Warm room
hot water
tea/coffee making facility
5 min walk to the metro
friendly reception

Couldnt find a fault!

I stayed here for 6 nights on 2 occasions in Jan 2013 while on business. Its very conveniently located near the EU Institutions. The rooms are nicely presented with a useful work-space and free wifi. Bed was comfortable and spacious. Tea 'n' coffee facilities are provided in the rooms which have an iron and board. My room at the rear was very quiet.
The TV service was a bit patchy, switching itself off every now and then. The breakfast is just about adequate and is eaten in the large foyer area. The foyer area deserves some mention; it contains a bar, table football and pool table plus a large screen for playing Wii games - a bit like a youth club.
Aloft does not have a traditional room service. Sandwiches and the like are available for purchase in the foyer area at night. The self service check-out works very well.

Stayed here from the 30th Dec- 1st Jan, it is a bit outside the city but the metro is close by and very frequent, my room was spacious, immaculate and the bed was very comfortable and quiet. I never heard a sound from any other guests and the hotel was fully booked, All staff that I met were very friendly and helpful. Highly recommend this hotel.
