When we arrived we found out they chage 4 euros for one hour of WIFI time.
They had one computer in the reception area which they said we could use 24 hours a day, but during the night when I tried to use it, I was told it was closed.

It looked like the person working at the reception desk wanted to sleep and didn't want to be disturbed. I suspect that as in poor countries, they don't have enough staff and or they don't pay well enough to have someone actually stay awake during the night, but instead they are supposed to work and sleep during the same shift. I suspect this because I saw a pair of shoes on the floor near the reception desk, and when I came down, I didn't see anyone sitting or standing behind the desk. Yet when he heard me coming, he stood up.

The next day I tried to connect my laptop directly to the Internet cable so I could upload and download my mail quickly, but I was told in a very authoritarian tone that this was not permitted either. I have done this often in other places so it all depends on the person making, enforcing or intterpreting the rules.

If you Internet access is important to you, then I would not recommend this hotel. Otherwise it was acceptable, except for a constand beep tone that we could hear coming from the hallway which sounded each thirty seconds or so. It might have been a low battery alarm on the smoke alarm, but I didn't investigate it to find out.
The show had mold around it, and the ceiling hadn't been painted after it had been patched, but it was clean enough.

Also, when I asked to talk to the owner of the hotel to express my dissatisfaction, I was told very bluntly "You can't talk to him."

I was travelling inEurope with my wife and teenage daughter. In Brussels, I wanted a triple room good convenient location at an attractive price without sacrifcing cleanliness & bit of comfort. I did quite a bit of research and settled on Hotel Albergo. The location is superb, within 5 min walk from Gare du Nord. Our Eurostar train from London arrived in Midi station, so we bought a 10 euro family pass (good for a whole day on public system) and took the metro to Gare du Nord. Walked from there, it was easy armed with google directions. In fact it is easier to walk from metro station Rogier. Come out of Metro on the Botanique side, look for Hotel Crowne Plaza, walk on the sidewalk infront of it, go under the under the bridge, cross the divided 2-way road, turn right, then turn left at the next corner. May be 3 - 4 minute walk, total. Note that Hotel ALbergo is next to Best Western (which is a bigger hotel, so easier to ask people for directions).
From Hotel Albergo you can walk to most of the attractions. Mustafa at the counter was very nice. He was very helpful! We liked our triple room, it was big with a private path. It was clean. I'd go back there next time!

Bathroom was covered in mold and our room had a horrible stench of mold. We had to go out and buy an air freshener. Located within walking distance of train stations. Overall in a quiet neighborhood where we felt relatively safe. Staff were helpful.

It's in a dodgy area close to the red light district and it looked dirty. On the other hand, its only five minutes walk from Gare de Nord train station and it's directly across from the Brussels Botonical gardens. I always felt 100% safe. The room I stayed in was essentially a studio: no door for the toilet of shower, just curtains, so I could see the toilet from my bed. The walls were paper-thin. I got zero sleep. You could hear the people in the lobby as if they were standing inside my room talking! There were all kinds of errors: I got a wake-up call when I didn't ask for one, the fire alarm went off one morning for no reason (we were told the croissants were baking and somehow the oven set off the alarm). There was hot water and things generally worked. Also they had an OK breakfast, which was free, and free internet in the lobby with the ability to print unlimited number of pages. The staff was helpful--Angelique was great. But all in all, my sleep is very important to me, and I just didn't get that sense of comfort here. It felt like I was staying at a hotel 1 star down from a Motel 6, if that's possible.
