It is hard to say whether the amateur and ignorant staff or the hotel management that allows a cheesy disco to spoil the hotel are worse. One = the other.
You will not sleep, you will get no service and you will wonder what on earth Best Western are doing.
Italian Tour Groups use it...what more can I say?

Rooms are great, but I didn't get to sleep before 4 every night of my stay because of the night club on the first floor. Several irate calls to reception did nothing. How the owner thinks he can get away with having a club and hotel and no sound-proofing is beyond me. And the rooms are hardly cheap either. Avoid like the plague!

Well, I have not written a review for a hotel before but with this one I think I should really give it a try.
I am a positive person so I will start from the positive aspects of it.
The rooms are beautiful, very large with king size beds. The bathrooms are also spectacular. My very first impression when I got into my room (both my rooms actually since I had my room changed) went beyond my expectations. The hotel is located close to the centre of Tunis, about 15 minutes walk from the famous avenue Bourguiba, which marks the heart of the city. The downside of its location is that the road is very busy and unbelievably noisy (Tunisians have some strong temperament went it comes to driving) which means that you won't be able to sleep late, unless you have ear plugs!
Yet the noisy road was NOT the worst thing about Maison Blanche.
First of all the staff at the reception was incredibly rude. I know that people working at 5-star hotels tend to be arrogant sometimes, but these ones were just rude, never smiled, never said thank you, just bad manners and unprofessional behaviour (to be fair, the rest of the staff was friendly but reception is really important, isn't it?).
Now, beware of the club on the first floor!!!! I stayed there for two nights and the room they gave me the first night was on the second floor, right above the club. Needless to say that it was IMPOSSIBLE to sleep until 4 in the morning. I asked for another room (I had paid £156 so I assume I had the right to sleep). They were unwilling to help me at the beginning but I insisted and they finally gave me another room on the 7th floor, which made a huge difference.
I really don't know whether I would recommend this hotel or not. I suppose it could be really nice for couples (the rooms have some oriental luxury in them that makes then almost romantic) yet certain aspects of it can turn your staying there into an ordeal. A noisy club that stays open until early in the morning and a rude, definitely unhelpful reception are things one cannot ignore. Service ought to be better at a 5-star hotel, that's for sure!

Despite being billed as a hotel for business people, it most definitely does NOT live up to that expectation.
The Brasserie turns into a nightclub open until 4am EVERY day of the week (I was there for 3 weeks and ended up finding a different hotel as i was due to be there for 5). The room is not soundproofed at all which means the music thuds up the walls and prevents a good nights sleep. Worse than this, if there is any trouble in there, the troublemakers are put out onto the road where they scream and shout without anything being done. On one occassion, I went to the (useless!) reception staff and asked them what they were doing about it but was met with a shrug and "what can we do about it"

Both restaurants serve nice food but the problem is actually getting it. I got seated in the Brasserie one night and waiting 20 minutes before being given a menu and asked what I wanted to drink. When you finally get the menu, they only have them in French so if you don't understand French, you're generally left with ham and turkey omelatte or margherita pizza because the servers cannot explain what the items are in English.

The reception and concierge staff are a little less than useless when it comes to actually knowing the area. I asked where there was an ATM on my first day, and got told it was over the busy road. Although there was one there, the closest one was actually attached to the cafe, right next door. I also asked where I could go to buy some toothpaste. Got told to go right down one of the roads adjacent to the hotel and find a place called Champion. Turns out there was a mini-supermarket right round the corner, around 2 minutes walk.

On some positive notes, the bedrooms/suites are very nice and very big; the wireless internet in the room is free and you won't wait long for a taxi to get out of the place.
