We stayed at Dar El Ma 3 years ago, Oct 2009, for two nights. The place was wonderful, located between the two most busy streets of the market, the house is big, comfortable and calm. The hostel has few rooms, what makes it more enjoyable. The people is nice and helpful.
The best two experiences were; sharing the BBQ with the another couple and listening to the "call to prayers" at nightfall from the roof of the house.
