A friend and I stayed here last fall and had a terrible experience. We arrived at Mariana after a 4-day tour to the desert. We asked our guide to walk us to Riad Mariana, since we didn't want to have to negotiate the square on our own with our luggage. When we arrived at the riad, the owner started berating our guide for being late (we arrived in the late afternoon/early evening, and had never been told we needed to be there by a certain time). I tried to explain to the owner that 1- we weren't late and 2- to the extent he was expecting us earlier, he should've made that clear to us, since we were the ones who kept asking our guide to stop to let us take pictures on the way back from the desert, so any delay was our fault. The owner kept berating our guide, who then left. After our guide left, the owner also left and my friend and I were alone with the clerk. We decided that we were really unhappy with the unbelievably rude and aggressive way the owner had treated the guide and decided to go stay at another riad. When we told the clerk we were leaving, he started yelling at us, then called the owner, who yelled at me over the phone. My friend and I called another riad, which sent an employee to pick us up. When the other riad's employee arrived, I walked out but the clerk physically blocked the doorway so that my friend couldn't leave. After a brief standoff, he said he'd let her leave if we paid him the equivalent of $20 USD for the 2-minute phone call we'd made to the other riad. I gave him a few coins, which he threw back at me. My friend, meanwhile, managed to slip past him, and we left. I've never been so happy to leave a place. The riad itself seemed fine (what little we saw of it) even though the courtyard was weirdly stuffy and unpleasant while we were there. To this day, I can't get over how badly the owner behaved, and the fact that the clerk basically tried to make us pay him to let us leave. The owner, by the way, did make us pay to leave, since he charged my credit card for our entire stay. Marrakesh is full of gorgeous riads owned by genuinely nice people. Mariana is not one of these.
