This riad is really nice. The staff are very friendly and very helpful. I would echo the comments of other reviewers. The manager said (if I remember correctly) that the riad used to house the grandfather of the current King's second wife and family. Some of the other riads in Marrakech and just knocked through houses but this one is more authentic. The rooms were simple but kept very clean and tidy. 15 mins walk through the souks to the square. A shop road the corner for bottled water etc. The mosque (Sidi Ben Silimane) was also an excellent landmark for taxis to find - there are so many riads that they will not know where the hotel is by name alone
Only a couple of minor gripes: the jacuzzi on the roof of the building looked in desperate need of a clean and had a film over the surface of the water. The map provided by the manager was also not very helpful (scribbled on the hotel business card). A simple larger hand drawing of the route to the souks and main roads/taxis provided on arrival would have been far more helpful. Lastly, the shower heads need to be replaced or descaled as they sprayed water all over the place and were not terribly effective.
Some general comments about Marrakech: this place is not for the faint hearted and is pretty full on in terms of sights, smells etc. The souks and square are great. There is not a huge amount in terms of other sight seeing - the palais bahia is nice but you will be finished in about 10-15 mins; the palais el badi which is excavated ruins in also worth a visit. None of the sights are well sign posted (even if you get a taxi to the destination) or for that matter well looked after - most have piles of rubbish littered around. The entrance fees also seem ridiculously low for tourists at 10Dirham. I would recommend cafe france as a nice place to watch the world go by in the square. I would strongly recommend the Bains de Marrakech where we had a hammam and massage which was incredible. Maison MK, Pepe Nero and Dar Najat were also very good places to eat.
I would provide a very strong word of caution though about people trying to direct you in the wrong way in order to walk you round in circles and demand payment for the pleasure. Trying to find a landmark or restaurant is usually complicated by (mainly, but not exclusively) young men trying to tell you that it is closed or that he will show you the way to go. They can be very pushy and persistent. As a rule ignore all offers for help - we mistakenly put our faith in someone showing us the way to the Ben Youssef Madrasa and we got very lost and just found the first taxi to take us back to the square - not a nice experience as you can find yourself very isolated very quickly in the maze of alley ways.
