During our stay in Morocco, we stayed at a number of places, and in retrospect this was one of the top Riads. The staff is what made the difference, in particular Omar who actually walked us to a restaurant, and showed us how to get to square. You're so bewildered the first time you're in Marrakesh, and all the alleys look similar. Anyway, it's a beautiful property, with a great location close to the square, souks and restaurants.
One drawback, the public sanitation company (so to speak) was working on the alley way in a one of the enclosed alleys (like a tunnel) right before the you make the last turn to the Riad entrance. They had constructed a wooden plank bridge over the trench construction site that we had to walk over most of the time we were going in and out. The first time it was a bit scary especially because it got relatively dark in the late afternoon. At night it's well lit, but they should turn on the light sooner. They made visible progress during the 3 days we were there, but I would ask, especially if someone has difficulty walking, or is using a cane or wheelchair.
There's a different way to go, but it's a bit confusing. You go straight pass the tunnel, and then keep making rights until you hit the main alley to the square (right next to the local Mosque).
Anyway, other than that, we had a terrific stay.
