The Dar Warda is a simple little riad in the north of the Marrakesh medina. It has four nicely appointed rooms on two levels around a lovely patio. It is very clean and quiet.
The staff are really helpful and friendly. I rate it excellent value for money. It was our first riad in Morrocco and I really didn't know how good it was until I tried other ones.
It is down a long and complicated "derb" (a network of alleys in a cul de sac) so it is well worth ringing ahead for the owner to meet you to collect your luggage (in a handcart!) and escort you to the riad.
The walk to the square is probably 15 minutes, but is very straightforward and you would have to try very hard to get lost.
I would certainly recommend it to couples looking for an atmospheric and traditional stay.
