Nothing negative, everything perfect.
Believe all the amazing reviews ... this place is a gem. I've travelled all over the world and my experience at Riad Andalib stands out as one of the best I've had.
The hotel is beautiful, with its amazing courtyard, and right by the medina (but accessible by car, so you don't have to walk through confusing streets, definitely an advantage).
The rooms are huge, even better than the pictures. We were so comfortable. The best WiFi access in Morocco that we found (important for us as we had to do some work at night).
But the best part of the experience was the staff. The owners (brothers) were amazing, always downstairs, attentive to every need. They helped me get medicine when I got a bit ill, by calling around and finding a pharmacy open (it was a holiday). Selma, a delightful young woman, attended to our every need when we ate at the restaurant, even offering to bring up food to the room when I was sick. She always greeted us with a smile. There is also always someone outside the Riad who will help you get a taxi and negotiate a price w/ the driver so they won't rip you off.
Another amazing thing: the food. The cous cous, pastels, and tagines were some of the best we had in morocco, for very reasonable prices. The breakfast was delicious and huge.
I can't say enough good things about this riad. Just stay there!!!
