The riad itself is beautiful and is tucked away in a quiet alley right next to the Maison Arabe. Service was impeccable, friendly, and unintrusive. Our room came with a TV and air conditioning, which was a welcomed surprised after spending several nights at other hotels which lacked these two amenities.
The reason that I rated this riad 4 instead of 5 stars is due to the location and the dining. We had stayed at a different riad earlier that was very conveniently located 5 minutes away from Djemaa el Fna and enjoyed being able to walk to the square so quickly. Riad Alwachma claimed to be a mere 7 minute walk to the main square but after walking for a good 10 minutes and finding that we were not even halfway to the square, we decided to turn back. Also, the area in which this riad is located did not seem to have any selection of restaurants so this may post a problem to visitors who wish to easily walk to restaurants.
We had reserved a dinner at the riad and while it tasted fine, we believed that both the appetizers and the deserts were prepared ahead of time and reheated instead of made to order. They informed other guests that they only needed a 10 minute advanced notice to "prepare" dinner, so we're pretty sure the dishes are simply reheated. This was somewhat of a letdown as we were expecting a wonderful home cooked hot meal.
All in all, we enjoyed our comfortable stay and thought the riad was very hospitable.
