My girlfriend and I spend a few days in Marrakech and we're very happy to have chosen Riad Zinoun. You'll find yourself in the center of the city just a one minute away from the Jemaa Al Fna and you'll feel like home inside the Riad. The workers there care very much and are soooo helpful and friendly.
They also tell you about the sights and supply you with useful information about Marrakech, so you never felt lost.
If you don't want to be in the middle of the hectic and prefer a hotel you'd better go for a hotel or riad outside of Marrakech (in Menara for example) but really I think being in the middle of the action and seeing and being part of this extraordinary culture is an absolute must!
Thank you Said and Nadira for those wonderful days
