I travelled here with my wife (on the Marrakech express, so obviously we are "of a certain age") and Riad El Arsat was perfect. The riad is surrounded by the bustle of the medina, ten minutes walk from Djemaa el-Fna (the old city's central plaza), but is a calm, quiet, refuge. There is a large garden with orange and palm trees, and constant bird song. Accomodation is in two houses at each end of the garden, renovated to a very high standard in what I think may be a Moroccan / Andalucian style.
Breakfast (pastries and coffee) was served either outside our room on the veranda overlooking the garden, or in the garden itself (or where-ever we wanted, I imagine). We also ordered dinner on the night we arrived, which was served in the salon.
The staff, under Meryam's management, operate to a high standard, and were always friendly, polite, and sympathetic.
On the roof terrace, which is higher than many surrounding properties, there are clear views of the snow-covered High Atlas mountains in the distance.
Basically, when the bedlam of the medina gets too much, relaxing at riad El Arsat is perfect.
