I stayed in Riad Bahia in January 2012 and I very much liked it. The Riad has a new owner since October and she gave us a warm welcome. The rooms are very nice and clean and the road has a good price/quality.
This was my second time in Marrakech. Last time I stayed closer to the Djemaa el Fna but walking there from the Riad is a nice walk..and not far at all.
The breakfast is standard..as in all Riads I stayed in. This is just the breakfast how it is in most places in Morocco.
I would stay here again and recommend it to others.
